Adaptive Dense Reward: Understanding the Gap Between Action and Reward Space in Alignment | Recently, many colleagues have discussed a key issue in ORM: if the evaluation is based solely on the final result, the reward signals obtained may be very sparse. Therefore, the Reward Model needs to generate different reward signals for different responses, which encourages learning from some responses that may not be entirely correct but contain reasonable information. The core insight of this paper from Alibaba lies in adaptively identifying important information and converting sample-level supervision into fine-grained, subsequence-level supervision, thereby making the reward and action space density more aligned with the input information density. The optimization goal and path are quite fundamental. However, the paper includes many extraneous elements, such as introducing adaptive masks to dynamically update the threshold for preference judgments and a Schmitt trigger. The author’s personal thought is more straightforward: if we simply focus on refining the reward generation process, for example, since a single reward for an entire response can be vague, why not allow a large model to run a pipeline that dissects the scoring dimensions? If we provide highly annotated CoT and reference scoring weights, and allow a large model to review and score progressively, this would be less about playing with algorithms and more about directly applying computational power to a longer, more detailed reward generation pipeline. Last time, a colleague from GDM mentioned that they scaled up computational power for generating PRM rewards, somewhat like applying self-consistency to RM, which reportedly yielded some benefits, although it is unclear how reliable this rumor is. |
The Graph's Apprentice: Teaching an LLM Low Level Knowledge for Circuit Quality Estimation | This Verilog instance dataset appears to be sizable and should be valuable. It could potentially be merged into our evaluation or used to cover an additional corner case. |
A Theoretical Perspective for Speculative Decoding Algorithm | This work by Mengdi Wang provides a theoretical analysis of speculative decoding, abstracting the decoding problem through a Markov chain formalization. The preliminary process involves generating draft sequences using a small model and then validating the tokens of these draft sequences with a large model. The first two claims made by the author are very strong: one provides the exact formula for the expected number of rejections in speculative decoding, indicating that the acceleration rate is inversely proportional to the distribution difference. The other proves that, under the condition of keeping the distribution unbiased, any unbiased algorithm will have at least as many rejections as speculative decoding, demonstrating that speculative decoding is optimal among this class of algorithms. The paper also introduces batch speculative decoding, which seems like a solid contribution. |
DynaMath: A Dynamic Visual Benchmark for Evaluating Mathematical Reasoning Robustness of Vision Language Models | In this work, the visual aspect merely serves to extend the set of mathematical seed problems. The approach, however, could be applied not only to mathematics. It includes 501 high-quality seed problems across multiple topics, each represented as a Python program. These programs are carefully designed to automatically generate a large number of concrete problem instances, covering variants such as numerical changes, geometric transformations, and function type variations. This approach is similar to the idea shared earlier regarding generating LeetCode-style problems from a template, which can then be dynamically extended into real LeetCode problems. This methodology seems useful for training models; with some adjustments, it could be leveraged in pre-training to create a small batch of synthetic data, yielding potential benefits. Out of the 501 seed problems, 227 are from existing visual mathematics datasets, while 274 are newly collected or developed. Beyond OOD evaluation, this approach can also support program-based evaluation, where a large collection of related algorithms/templates can be used to test the internal robustness of a single algorithm/template. Additionally, tricks could be applied to these algorithm templates, such as constructing cases like "how many animals are in the cage if there are chickens and rabbits", to test the degree of pattern solidification in the model. This is an effective and low-cost direction that can provide valuable insights. |
A Deep Dive Into Large Language Model Code Generation Mistakes: What and Why? | This paper analyzes code generation errors in large language models, using GPT-4 and Gemini Pro 1.0, and benchmarks such as HumanEval-X and CoderEval. It provides a valuable analysis of errors occurring in language model code generation. The paper identifies seven main categories of errors: conditional errors, garbage code, mathematical formula and logic errors, minor output formatting errors, operational sequence errors, API misuse, and indexing errors. In the cause analysis, apart from corner cases and training gaps, several key insights are offered: 1. Misleading coding conventions and guidelines; 2. The impact of In-Context Learning (ICL). Both 1 and 2 have similar effects: ICL is not necessarily wrong, but it may introduce strange influences in subsequent outputs. There seems to be much potential for further exploration here. 3. Misleading function documentation. One hypothesis is that LLMs somehow learn a pattern in code generation where the function signature is expected to fully align with the implementation. 4. Sensitivity to position. |
Scaling Laws with Hidden Structure | This paper is highly recommended for reading, as its modeling approach is fundamental. The author seems to believe that neural networks can effectively learn discrete distributions through hidden factorial structures in the data. From my reading, the assumption is that each discrete element (though not explicitly mentioned in the paper, it can be intuitively linked to tokens) is mapped to a learned vector, and any unknown or known factorized embedding can be represented as a nested distribution satisfying the factorial assumption. Additionally, the paper observes that the learning speed is related to statistical complexity χ, suggesting that MLPs can leverage the implicit product form of the target distribution to improve learning efficiency. The paper also argues that generalization ability is related to the connectivity of the factorization graph and its statistical complexity. Although the experiments are somewhat toy-like, the findings can be linked to many phenomena in large language models (LLMs). From a circuit perspective, I feel that it is relatively clear how LLMs learn individual functions, and this research could clarify this further. The most valuable aspect of the paper in terms of Mechanical Interpretability is understanding where traditional grammar or CFG assumptions do not align with text grammar and how to construct CFGs (or multiple CFGs) that resemble text grammar but are controllable. This would help identify the subtle boundaries and mechanisms of whether and how the learning occurs. |
Varco Arena: A Tournament Approach to Reference-Free Benchmarking Large Language Models | The quality of this paper is not particularly high. It introduces a single-elimination tournament approach to reduce the number of comparisons required to achieve a robust Elo score. However, this is an emerging direction that I find promising. Recently, I came across another paper that uses multiple non-Elo algorithms to model other statistical significances based on different models' responses to the same prompt. This paper could be considered a pioneering work in the field, opening up a small new area. As for Arena, there are a lot of assumptions that are problematic. For example, it attempts to represent user profiles, but which types of users does it represent? Are different users truly consistent? The paper provides a simple win/loss analysis, but what about clustering and analyzing response patterns? How are user preferences reflected? There's a lot to explore from a statistical perspective. Additionally, the chatbot arena approach itself is not particularly efficient. |
Next-Token Prediction Task Assumes Optimal Data Ordering for LLM Training in Proof Generation | This paper raises an interesting and important issue. The related work gives the impression that there has been insufficient research into the impact of data ordering in LLM training. The paper utilizes LEAN and HH. The author introduces a new data ordering method, called intuitive ordering, in which the relevant intermediate supervision for each proof step always appears to the left of the proof step. Personally, I feel that this is somewhat of a toy model because it’s difficult to find this kind of intuitive ordering in pretraining data. Nevertheless, I still appreciate articles that introduce new problems. |
Vision-Language Models Can Self-Improve Reasoning via Reflection | This is a relatively good A+B paper that introduces an iterative self-training framework, R3V, to enhance vision-language reasoning abilities through reflection on self-generated CoT (Chain of Thought) reasoning. The method itself is not particularly groundbreaking, but it is still worth reviewing for tuning experiences and the observed improvements in performance. |
GWQ: Gradient-Aware Weight Quantization for Large Language Models | The idea is simple, intuitive, and effective. The proposed GWQ method retains the top 1% of weights with the largest gradient absolute values in FP16 precision, while quantizing the remaining weights to a lower bit format, achieving a low quantization loss. This can be considered a parameter quantization version of Speculative Decoding. |
Can Large Language Models generalize analogy solving like people can? | This is an out-of-distribution (OOD) task where participants are asked to infer a new letter string based on a given transformation rule. The performance of models and humans is compared, and interestingly, adults and some LLMs (such as GPT-4o and Llama-3.1 405B) outperform children in this task with the Latin alphabet. However, Claude-3.5 and Gemma-2 27B perform slightly worse. This observation highlights the rare lack of robustness in Claude-3.5-Sonnet for OOD tasks, whereas Llama-3.1-405B does not perform poorly. It might be worthwhile to add Llama-3.1-405B as a baseline in our OOD benchmark comparisons. |
Thinking Forward and Backward: Effective Backward Planning with Large Language Models | The paper proposes a backward planning algorithm where the LLM first generates a backward plan, then reverses the sequence and self-validates it. This approach helps LLMs avoid inherent biases in backward planning, generates more diverse candidate plans, and utilizes the asymmetry between the forward and backward directions of planning problems. The benchmarks used are limited to three constructed tasks: graph planning, array transformation, and block world tasks. However, the experimental design is quite interesting; it employs breadth-first search (BFS) to compute the number of steps for both forward and backward searches. ING-VP used a similar approach, and while many recent reasoning benchmarks have not, it is actually possible to derive the structure of a Reasoning Directed Acyclic Graph (RDAG), where for steps that are well-defined, the nesting depth and total steps can be clearly calculated, which can provide valuable new insights. |
How Far is Video Generation from World Model: A Physical Law Perspective | This paper explores the ability of video generation models to discover physical laws, particularly the ability to identify these laws purely from visual data. The quick takeaway is that diffusion models and insufficient data alone cannot solve the out-of-distribution (OOD) generalization problem. During the generalization process, the model tends to refer to similar training cases rather than learning universal rules. Future research should focus on improving models to better understand and apply physical laws. This is somewhat similar to the characteristics of LLMs, but it appears that the knowledge learned by diffusion models is shallower (possibly due to the lower information density in visual data, making it harder to extract rules). Earlier this year, during an ICLR discussion with Professor Tan Xu and Xing Chao, we talked about why diffusion models rarely mention "grokking." If one is learning explicit rules or patterns like resolution or extraction, it is relatively smooth. A follow-up paper analyzing diffusion model grokking from the perspective of physical laws could be a very decent contribution. |
Evaluating Creative Short Story Generation in Humans and Large Language Models | This is not a static benchmark, so it cannot be included in existing evaluation systems, but it quantifies some points that might already be known: 1. Stories generated by models tend to have higher vocabulary and syntactic complexity than those generated by humans, but they have lower readability. 2. Human-generated stories exhibit higher vocabulary diversity. They have lower complexity but higher diversity, which could be an interesting point. 3. Humans are more likely to use pronouns and often write from the first or second-person perspective, while models tend to favor the third-person perspective. 4. Humans' story transitions and plot twists create a greater sense of surprise, meaning that humans have more creative twists, whereas models tend to be more mundane and logical. I am also quite curious about how Robert trains his models, as the results still seem intriguing. |
Improving Steering Vectors by Targeting Sparse Autoencoder Features | The paper primarily addresses the issue of steering vector intervention. They control the behavior of language models by adding steering vectors, which are implemented by inserting activation vectors during the model's forward propagation process. In this work, they increase the impact prediction by inserting the steering vectors, thus achieving a certain degree of controllability (SAE-Targeted Steering, SAE-TS). The aim is to achieve more precise steering control by measuring the impact of steering vectors on Sparse Autoencoder (SAE) features. This method seems to have significant implications for alignment, especially during supervised fine-tuning (SFT), where the prediction of the impact of any single data point could be highly important. It is worth considering how to follow up on this approach. |
Adaptive Sparse Allocation with Mutual Choice & Feature Choice Sparse Autoencoders | Recently, it seems particularly fitting to write a position paper on how to use Sparse Autoencoders (SAE) and techniques like the logit lens to understand model parameters and achieve controllability over model behavior. There seems to be a small technical breakthrough in this area, with slightly novel papers emerging almost every day. This paper proposes framing the token-feature matching problem as a resource allocation problem constrained by a sparsity budget. Existing TopK SAE methods solve this allocation problem under the constraint that each token can match at most K features, but they fail to fully leverage the advantages of adaptive computation. Therefore, they propose two new SAE variants: Feature Choice SAEs and Mutual Choice SAEs. Feature Choice SAEs relax the constraint that each feature can match at most M tokens, addressing the sparse allocation issue. Mutual Choice SAEs remove the constraint on token-feature matching numbers, allowing free allocation within the total sparsity budget. The new loss design they propose is somewhat similar to MoE load balancing. |
TableGPT2: A Large Multimodal Model with Tabular Data Integration | This is a project from Zhejiang University's Jake Zhao Junbo, which focuses on building a comprehensive pipeline for table understanding. It includes pretraining and other components, and the approach is quite detailed. The benchmarks and datasets involved in the paper could be worth reviewing for potential references or reuse. |
Context Parallelism for Scalable Million-Token Inference | The paper introduces Context Parallelism (CP) to optimize long-context LLM inference. It specifically focuses on long contexts and presents two lossless, accurate circular attention variants: pass-KV and pass-Q. Additionally, scalability tests are conducted across multiple nodes. |

Human-inspired Perspectives: A Survey on AI Long-term Memory | The focus is on several concepts presented in this paper:\1. The paper introduces several types of human memory: episodic memory, semantic memory, and procedural memory. It maps the first two to non-parametric memory and the latter to parametric memory. Within the context of this survey, the authors expect that various episodes and semantics are to be within the context accepted by language models, rather than associations generated within the model itself. This may not necessarily be a correct belief, but it is worth considering.\2. Furthermore, the paper proposes a memory management mechanism, emphasizing that adaptive storage, adaptive retrieval, and adaptive forgetting handle different types of information separately. These three operations are defined very concisely: storage, retrieval, and forgetting. Currently, generally speaking, LLMs rarely explicitly manage forgetting, including agents; this might be achievable through those circuit control-based schemes that have appeared in many recent papers. |

GPT for Games: An Updated Scoping Review | This survey offers a well-structured perspective, introducing two noteworthy aspects. Firstly, the title clearly defines the scope (2020-2024), providing a focused temporal range that avoids an exhaustive historical review. Secondly, it presents a novel approach to literature selection, suggesting that the process itself can be a relevant research topic. While most current surveys are AutoSurveys, the method used here could inspire studies analyzing how literature for a survey topic is selected, based on previous reviews. The paper is divided into three main areas: 1) Game Generation, 2) Agent Creation in Games, and 3) Game User Research. In the Game Generation section, the study summarizes methodologies that generate entire game content based on frameworks like stories or programs, covering granularity levels from stories and missions to levels and characters. It also discusses design development through user prompts and interaction with large language models (LLMs), where LLMs primarily serve as tools for quickly generating various layouts and mechanisms. In the context of interactive gameplay, the paper likens this approach to tabletop RPGs, where LLMs provide story content, user experience enhancements, and real-time creative support. This field shows significant potential, with only around 30 papers selected for review, and many appear to be standouts in a limited field. Research in game user studies also appears sparse, with only a few papers in this category. |

GameGen-X: Interactive Open-world Game Video Generation | This paper presents the OGameData dataset, which supports text-to-video generation and video continuation tasks, enabling models to generate high-quality, open-domain game videos with long sequences. It integrates character interaction and scene content control within video generation. As one of the earliest works in China paralleling Google’s Genie, the follow-up results appear promising. After reviewing their promotional video, minor issues in scene transitions were observed, though overall performance is impressive. The keyboard control feature is notably commendable. |
Latent Paraphrasing: Perturbation on Layers Improves Knowledge Injection in Language Models | |
Decoding Dark Matter: Specialized Sparse Autoencoders for Interpreting Rare Concepts in Foundation Models | Based on SAE training, an inclination parameter t is introduced to encourage the model to better represent tail concepts. |
Mitigating Tail Narrowing in LLM Self-Improvement via Socratic-Guided Sampling | Impact of long-tail data is highlighted, and this phenomenon is indeed quite pronounced. During the model's self-improvement process, oversampling simple queries and undersampling complex ones lead to a concentration of distribution on high-probability data. High-probability data coincidentally aligns with the model's internal common patterns, ultimately resulting in mode collapse. We also have worked on self-improvement, and we find that this issue is both common and significant. The solution presented in this paper appears intuitive, using various forms of guidance to identify and resample tail data. Based on personal experience, seemingly less elegant methods can often be insightful and practical; in this case, “less elegant” refers to the use of four types of guidance by Professor Huang and Professor Guitao, which lack obvious intrinsic logical connections. The ablation study suggests that the proposed state reset approach is generally more effective, where this state reset is somewhat similar to reverting to a prior reasoning step after multiple unsuccessful attempts at the current step |
Physics in Next-token Prediction | Recently, TeleAI has published quite a few works that may not be highly effective but are quite imaginative, such as SentenceVAE and a collaboration with BAAI on continuously scaling model pre-training up to 1 trillion parameters. In this paper, a new formula is proposed to quantify the energy consumption required for information transmission in the context of Next-token Prediction (NTP) as an information compression process. Consistency with the OAI Scaling Law is also derived |
Self-Evolved Reward Learning for LLMs | This work proposes a self-evolved reward learning approach. The key innovation compared to SPIN and previous methods is that this approach self-evolves the RM through a feedback loop using the RM itself. The LLM serves as the RM, generating feedback on the dataset that is subsequently used to refine its own learning. This iterative ”feedback-then-train” loop allows the RM to self-evolve over time, gradually improving its performance. It can also generates high-quality preference data and reduce the reliance on human-annotated data. 'Self-Improving' topic is finally gaining momentum and becoming more popular in the field. |
Constant Acceleration Flow | The work on Diffusion really involves a lot of explicit physics concepts. |
Generalizability of Memorization Neural Networks | The paper presents a systematic theoretical analysis of generalizability of memorization neural networks. It provides a formula modeling the minimum number of parameters required to memorize any dataset sampled i.i.d. The research demonstrates that some commonly used memorization networks do not have generalizability even if the dataset is drawn i.i.d. from a data distribution and contains a sufficiently large number of samples. This work also provides complexity analysis. Recommended reading for those interested in interpretability studies. |
Lingma SWE-GPT: An Open Development-Process-Centric Language Model for Automated Software Improvement | The fundamental concept is that after modeling the code trees from the majority of GitHub repositories, GitHub can theoretically serve as a simulation environment for scaling RL. This approach is viable because GitHub contains comprehensive data with natural interaction records, even after filtering. Compared to conventional RL environments, it additionally provides codebase summaries, essentially functioning as a summarization based on global observations. The LingMa paper collected approximately 90,000 PRs from 4,000 repositories. The data underwent filtering to ensure code change quality and relevance, and then followed STaR's approach for training, implementing a fixed three-stage CoT (Chain of Thought) training framework: repository comprehension, fault localization, and patch generation. They employed their classic rejection sampling method, using two metrics - fault localization accuracy and patch similarity - for data filtering to ensure high-quality synthetic data. This suggests promising potential for scaling Decision Transformer/RL using standard code bases as initialization. |

Interpretable Language Modeling via Induction-head Ngram Models | A notable contribution that builds upon infini-Gram, which computes next-word probability distributions through longest suffix matching in reference corpora. The research introduces induction heads and employs custom neural similarity metrics for efficient search of potential next-word completions in input contexts. This process enables Induction-Gram to provide ngram-level justification for each generated word. Through this approach, it allows for coarse-grained evaluation of how language models predict subsequent words. |
Evolving Alignment via Asymmetric Self-Play | The paper presents a combination of RLHF and evolutionary approaches, essentially layering evolution over RLHF without substantially addressing the inherent preference modeling issues in RLHF. The work's notable insight lies in simultaneously optimizing both Creator's generation strategy and Solver's response strategy. This approach suggests a broader application beyond Creator roles - one potential direction for scaling RL on pretrained corpora involves a model with basic text comprehension capabilities, where a Rewriter & Creator fits the distribution of information between the question set and the original pretraining corpus, which aims to cover all essential information from the original pretraining corpus with minimal questions. The other component, similar to their Solver, focuses on problem optimization. The paper's implementation of minimax-regret, increasingly referenced in recent multi-agent works, merits review. While the paper's core claimed contribution is evolving previously uncovered prompts to encompass more scenarios, this advancement might be considered incremental. |

Reasons and Solutions for the Decline in Model Performance after Editing | TLDR: The method is not the focal point; rather, two interesting issues with model editing are identified: (1) There is a strong correlation between the explosive growth of the L1 norm in parameter layers during editing and the accuracy of the editing. When the L1 norm experiences explosive growth, model performance declines. (2) The diversity and sequence length of the editing targets have a significant impact on model performance. Higher perplexity in the editing target results in a more severe performance drop. If the L1 norm of the edited layer serves as a good indicator of catastrophic forgetting, this raises two valuable research questions: (1) Can the L1 norm be refined to focus on the features most affected by editing, potentially providing more insights? (2) The higher the perplexity of the editing target, the more severe the performance decline. In this paper’s case, perplexity is compared across several problem types, such as true/false questions, multiple-choice, and generation. This raises the question of whether, for certain problem types, the stability of model patterns may have a greater impact on performance than the robustness of memory for multiple specified facts, as editing may unintentionally disrupt certain higher-order pattern stability. |
AndroidLab: Training and Systematic Benchmarking of Android Autonomous Agents | Highlights the shift from niche to mainstream in agent benchmarking. Presents a smartphone-side agent benchmark where Table 1 shows the 4o model outperforming Claude by a margin of three points, although interestingly, the highest logical operation rate is from Gemini-1.5-Pro, despite its underwhelming performance overall. This benchmark may be a starting point for integrating simulation-based agent benchmarks. |
BitStack: Fine-Grained Size Control for Compressed Large Language Models in Variable Memory Environments | Proposes an intuitive method for compression without additional training, enabling dynamic size adjustment for large language models (LLMs) in variable memory settings. The approach continuously decomposes weight matrices, observing the residuals' impact with a calibration set, ranks them by importance, and dynamically loads/unloads parameters, which may prove useful in practical applications. |
Representative Social Choice: From Learning Theory to AI Alignment | Although not specifically an alignment tool, this sociological model has potential applications in predictive analysis, providing flexibility in setting up population-based preferences across different agenda topics. Extending it to support composite population distributions could be valuable for simulating public opinion dynamics. |
Nearest Neighbor Normalization Improves Multimodal Retrieval | Introduces a simple yet potentially effective incremental technique using the embeddings of the k-nearest neighbors to estimate retrieval bias, instead of relying on a global bias. This plug-and-play approach is straightforward to implement. |
Constraint Back-translation Improves Complex Instruction Following of Large Language Models | Addresses the practical challenge of following complex composite instructions, highlighting back-translation as a potential solution. This topic lends itself well to academic exploration, as it may yield interesting insights without requiring extensive resources. Future work might consider leveraging CriticGPT-like data to further enhance this approach. |
Length-Induced Embedding Collapse in Transformer-based Models | This paper identifies an issue where, as sequence length increases, the self-attention mechanism essentially functions as a low-pass filter, causing embeddings to retain only their low-frequency components. This observation is consistent with recent findings, such as those in Xiaomi's paper "HoPE: A Novel Positional Encoding Without Long-Term Decay for Enhanced Context Awareness and Extrapolation." It suggests that adjustments targeting this low-frequency dominance could be made through relatively cost-effective methods. |
Commonsense Knowledge Editing Based on Free-Text in LLMs | Builds on prior knowledge editing research, noting that commonsense knowledge resides in both MLP and attention layers. Unlike structured triples, commonsense knowledge here reflects simple causal reasoning, such as "feeling thirsty, so drink water," suggesting further exploration of which layers contain specific types of commonsense knowledge. |
What Happened in LLMs Layers when Trained for Fast vs. Slow Thinking: A Gradient Perspective | This paper offers insightful analysis on differences in model behavior under fast versus slow thinking training modes. Through gradient analysis using the nuclear norm of singular value decomposition (SVD) to represent the characteristics of the gradient matrix, it observes that without Chain of Thought (CoT) or with simplified CoT, gradients in shallow layers are larger and show notable differences between layers. In contrast, when detailed CoT is applied in slow thinking mode, gradients become more consistent across layers. A key takeaway is that under the slow thinking mode, gradients can differentiate correct responses from irrelevant ones, with instruction-tuned models aligning more closely with the behavior of the original pretrained model. This analysis suggests that appropriate step-wise division may indeed enhance the robustness of LLM-based agents. |
Unpacking Failure Modes of Generative Policies: Runtime Monitoring of Consistency and Progress | The approach and concept are intuitive. The proposed STAC essentially analyzes the statistical distance between time steps induced by a policy's action distribution within a simulated environment. Excessive deviations in this distance indicate potential failure. This idea is somewhat analogous to world modeling, albeit a simplified one based on post-action world simulations, and represents a valuable direction. |
VL-Cache: Sparsity and Modality-Aware KV Cache Compression for Vision-Language Model Inference Acceleration | Using KV-Cache compression for video understanding models seems a reasonable approach. However, the implementation appears loosely related to multimodal processing. It introduces a post-visual attention mechanism to calculate cross-layer sparsity and within-layer token importance, dynamically adjusting the window size to select significant visual and language tokens, thus enhancing cache hit rates. For long video comprehension, one could consider compressing multiple frames within a slot under the same perspective or creating hierarchical structures. Representing continuous frames as sequential depictions of changes in the first frame could be an alternative for video representation. |
MoLE: Enhancing Human-centric Text-to-image Diffusion via Mixture of Low-rank Experts | The authors conducted thorough data collection and modeling of human faces and hands, gathering a dataset of over one million high-quality portrait images in various scenes. |
All or None: Identifiable Linear Properties of Next-token Predictors in Language Modeling | The paper is heavy on formulas without experiments; a detailed review is needed. The claims are quite strong. Prior models assumed diversity in representation and equal dimensions, allowing linearly invertible transformations for distributionally equivalent models. Here, distributional equivalence is based on high-dimensional vectors corresponding to semantic and syntactic patterns. Loosening prior conditions, the paper introduces additional linear properties that may not be intuitively interpretable, showing that equivalency can hold without satisfying both previous requirements. This warrants further analysis. |
Learning to Achieve Goals with Belief State Transformers | This seems to be a variant of FIM tailored for long-text generation, differing from standard FIM loss. It incorporates a forward encoder and a backward encoder to encode prefixes and suffixes, respectively, with heads predicting the next word after the prefix and the preceding word before the suffix. The training objective combines both forward and backward Transformer goals, emphasizing the continuity between prefix and suffix, especially during inference where the forward model uses the prefix with an empty suffix to generate text in an autoregressive manner. |

Multi-student Diffusion Distillation for Better One-step Generators | The research demonstrates improved generation quality and inference speed by distilling conditional teacher diffusion models into multiple one-step generators. The dimensional decoupling effectively reduces the learning complexity of the generation process. |
Predicting Future Actions of Reinforcement Learning Agents | The study explores two approaches for predicting future events: accessing agent internal states and synthetic solutions. Among the three internal state methods examined (most frequently accessed simulation actions, action dependency trees, and LSTM hidden states), the first method showed significant improvements in action and event prediction accuracy. This suggests that despite being RL-trained agents, the prediction accuracy relies more on identifying fixed patterns rather than state activation and action logic relationships. |
ML Research Benchmark | This solo-authored paper introduces seven agent tasks: MiniPile, LLM Merging, Edge LLM Compression, Edge LLM Training, Math Reasoning, LLM Efficiency, and BabyLM. The benchmark requires an agent workflow approach, allowing flexibility in model architecture selection while constraining resources to a single A100 40GB GPU and 24-hour time limit. The research indicates Claude-3.5 Sonnet outperforms GPT-4 on most tasks. |
Decoupling Semantic Similarity from Spatial Alignment for Neural Networks | The research introduces Semantic Representational Similarity Matrices (RSMs) that decouple localization and semantic information from traditional RSMs. It addresses spatial misalignment through set matching problems and demonstrates the differences between conventional and semantic RSMs using a purpose-built toy dataset of partially overlapping image patches. |
Less is More: Pre-Training Cross-Lingual Small-Scale Language Models with Cognitively-Plausible Curriculum Learning Strategies | The study utilizes the BabyLM dataset to evaluate fine-grained curriculum learning strategies. Three objective curricula are defined: GROWING, INWARDS, and MMM. The research demonstrates that language acquisition theory principles, particularly the "moderate effect," can be effectively applied to curriculum learning in pre-training datasets. The findings suggest careful consideration of dependency granularity in curriculum design. |
VisAidMath: Benchmarking Visual-Aided Mathematical Reasoning | This benchmark from DAMO Academy presents 1,200 mathematical problems with explicit and implicit visual contexts, covering plane geometry, solid geometry, analytic geometry, and calculus/functions. The geometric reasoning components represent particularly valuable contributions to the field, addressing a previous scarcity of such datasets. |
Online Intrinsic Rewards for Decision Making Agents from Large Language Model Feedback | The research emphasizes the potential of synthesizing dense rewards from natural language descriptions in reinforcement learning (the most valuable quote), where irony, refusal to answer, stopping talking, and a large number of long-winded replies all contain a certain positive or negative signal. This signal is not even one-dimensional like agreement-opposition. There may be more complex emotions and many things that can be used as rewards, which current RLHF systems may not fully capture. |
BUZZ: Beehive-structured Sparse KV Cache with Segmented Heavy Hitters for Efficient LLM Inference | The paper presents a sparse caching approach combined with sliding window mechanisms to capture recent information, dynamically segmenting historical tokens and prioritizing important tokens within local neighborhoods. Could be useful for long video modeling. Peak identification is achieved through local maximum sampling to preserve critical information within segments. |
Adaptive Paradigm Synergy: Can a Cross-Paradigm Objective Enhance Long-Tailed Learning? | The research examines the relationship between self-supervised and supervised learning, introducing Adaptive Paradigm Synergy (APS) as a novel cross-paradigm objective. The approach addresses long-tail distribution challenges by dynamically adjusting the uniformity of latent space structures. |
Testing GPT-4-o1-preview on math and science problems: A follow-up study | The study evaluates GPT-4-o1's performance on advanced scientific computation and mathematical problems, identifying specific weaknesses in spatial reasoning and physical concept understanding. Notable findings include significantly lower performance on "arbitrary number" problems compared to "no calculation" and "motivated number" problems. The interesting part is finding such a blindspot of o1. |
Machine Unlearning using Forgetting Neural Networks | The research extends MLPs with a multiplicative forgetting function, demonstrating Ebbinghaus-like forgetting curves under variable forgetting rates using MNIST data. Ranking forgetting rates proved most effective among the forgetting function types, with multiple learning-forgetting phases improving test data generalization. Could be a plug-and-play method. |

Decoding Diffusion: A Scalable Framework for Unsupervised Analysis of Latent Space Biases and Representations Using Natural Language Prompts | The study analyzes h-space vectors extracted through U-Net layer outputs to observe evolution during the diffusion process. While the parameter analysis isn't particularly robust, it effectively demonstrates that the model learned gender biases related to occupations. This represents a potential latent pattern rather than a definitive higher-order semantic pattern. Visualization of h-space vectors revealed vector clusters containing fixed entity types such as square plates, soup pots, and sandwiches. However, across different clusters, it suggests that higher-order concepts related to "eating" may not have been well-learned. |
Deep Optimizer States: Towards Scalable Training of Transformer Models Using Interleaved Offloading | The infrastructure-focused paper presents logical findings, particularly relevant for MoE-type models. Key discoveries include significantly reduced GPU memory utilization during update phases and low PCIe link utilization during backpropagation and updates. The solution involves subdividing optimizer states, implementing interleaved parameter updates offloading on GPUs, overlapping optimizer subgroup movement and execution between GPU and CPU, efficiently placing and moving gradients, and utilizing higher precision PCIe transfers to avoid costly memory allocation. A performance model was developed but not thoroughly examined. A model-side insight regarding MoE relates to its comparison with an extremely wide dense model. In OAI's "Scaling Laws for Neural Language Models", Figure 6 analysis mentions "When we exclude embedding parameters, the performance of models with different depths converge to a single trend. Only models with fewer than 2 layers or with extreme depth-to-width ratios deviate significantly from the trend.". The exact definition of "extreme" remains unclear. Previous observations suggest MoE models achieving similar loss don't match the performance of corresponding wide models, which could be verified using hellaswag. Hyper-Connections technology shows potential for addressing the width-to-depth ratio optimization in MoE models. |

However, the educational thinking patterns summary provides valuable insights, including: Critical Thinking, System Thinking, Computational Thinking, Design Thinking, Metacognition, Data Literacy, Creative Thinking, Collaborative Thinking, Abstract Reasoning, Spatial Reasoning, Quantitative Reasoning, Logical Reasoning, Analogical Reasoning, and Scientific Reasoning. |
Offline Reinforcement Learning with OOD State Correction and OOD Action Suppression | Demonstrates the mutual influence between RL and Imitation Learning. LLM pre-training typically develops ICL capabilities, which essentially combines or retrieves stored patterns rather than solving entirely new problems. The paper addresses OOD states in offline RL that can lead to catastrophic failures during online deployment. The proposed solution introduces regularization to map OOD states to their nearest known states, following a similar pattern-matching approach. |
Fourier Head: Helping Large Language Models Learn Complex Probability Distributions | Introduces the Fourier Head, which uses linear layers to extract Fourier series coefficients, quantizing them into equidistant intervals. The approach evaluates Fourier PDF values at interval center points to return likelihood values as classification distributions. This method appears more mathematically natural than linear layers for modeling CoT/Diffusion-based LLM states, as it inherently models continuous data distributions closer to semantic spaces. |
Fast and High-Quality Auto-Regressive Speech Synthesis via Speculative Decoding | Applies speculative decoding to speech synthesis, leveraging the hierarchical structure of codebooks in speech and music (encodec/soundstream). |

Learning and Unlearning of Fabricated Knowledge in Language Models | Initial findings indicate that in CPT learning of new knowledge, facts conflicting with common sense persist longer than ordinary facts or randomly scrambled facts, potentially causing inappropriate triggering effects. |
MCPDial: A Minecraft Persona-driven Dialogue Dataset | Presents a dataset containing 250 Minecraft NPC character descriptions with corresponding player character descriptions and 49 hand-crafted dialogues. Introduces a novel pipeline for generating character-driven game dialogues based on collected character descriptions and dialogues, demonstrating application within Minecraft. |
How Does Critical Batch Size Scale in Pre-training? | Introduces the concept of Critical Batch Size (CBS), marking the threshold where increased data parallelism no longer yields significant benefits. Experiments using C4 suggest CBS scales primarily with data size rather than model size. Studies included models up to 1.2B parameters, examining CBS patterns by controlling model and data size variations. The conclusions require further verification considering the data quantity is not big engough. CBS appears to be an optimizable hyperparameter, though its inclusion in usual scaling law iteration fitting may limit additional value. |
L3Ms -- Lagrange Large Language Models | Formalizes SFT and alignment as a constrained optimization problem, aiming to minimize task perplexity while meeting application-specific minimum requirements. Introduces expectation and uniform constraints, applying minimum rewards to generated prompt-response pairs and probability lower bounds for inequality satisfaction. Mathematically, it discourages fixed patterns while minimizing model impact in prompt-to-response conversion, using Lagrange multipliers for constraint handling. |
Mind Your Step (by Step): Chain-of-Thought can Reduce Performance on Tasks where Thinking Makes Humans Worse | The conclusions and narrative approach lack robustness. While drawing from cognitive psychology cases where human performance decreases with overthinking, the experiments lack robust control over CoT implementations and their impacts on model performance. The work appears to make claims about cognitive psychology alignment without sufficient investigation of underlying mechanisms connecting model behavior and human cognition. |
Beyond Interpretability: The Gains of Feature Monosemanticity on Model Robustness | While the experiments could be more robust, the methodology offers insights. Training simple linear classifiers on pre-trained features and evaluating monosemantic feature performance under various noise conditions may provide an efficient way to observe internal model features, dependent on clean monosemantic decomposition. |
Causal Interventions on Causal Paths: Mapping GPT-2's Reasoning From Syntax to Semantics | Reveals that GPT-2's initial 2-3 layers primarily capture syntactic structure, with attention heads showing high focus on causal delimiters. Identified attention heads with increased causal relationship sensitivity. The methodology of replacing key words in causal sentences to create non-causal versions and observing prediction impacts through layer-wise loss calculation could be valuable for future research. |
Reducing the Scope of Language Models with Circuit Breakers | Represents a growing trend in parameter-task orthogonality-controlled fine-tuning. The approach identifies and controls minimal relevant parameters while decomposing instruction task requirements, often incorporating orthogonalization definitions. Applicable for implementing selective response rejection or improved format following, showing mechanistic coherence. |
Efficient Training of Sparse Autoencoders for Large Language Models via Layer Groups | Presents a layer grouping approach for efficient sparse autoencoder training, significantly reducing training costs while maintaining reconstruction quality and downstream task performance. Results indicate shared common features between adjacent layers in Pythia. The grouping strategy involves clustering layers based on angular similarity before training an SAE for each group, offering a practical approach to efficient SAE training. |

The Geometry of Concepts: Sparse Autoencoder Feature Structure | The study defines three scales in neuroscience—atomic, brain, and galaxy—and analyzes models across these scales. On the atomic scale, it eliminates distracting features, revealing parallel directions in related words, such as Vienna’s alignment with Austria, similar to Bern’s alignment with Switzerland. The brain scale introduces a notable lobe structure, with a prominent emphasis on code and math. At the galaxy scale, the point cloud (each point being a SAE Feature) shows anisotropy, with feature representations concentrated and not isotropic. The study highlights that "the underlying density varies with radius and, for a high-dimensional Gaussian distribution, is strongly concentrated around a relatively thin spherical shell." Additionally, clustering entropy is lower at the intermediate layers. The conclusions at the galaxy level are worth further contemplation. Marked for follow-up. |
Shopping MMLU: A Massive Multi-Task Online Shopping Benchmark for Large Language Models | This benchmark, designed to evaluate LLMs as shopping assistants, is straightforward and focused. It can serve as a reference for specific downstream tasks, potentially as part of a CPT (Customer-Personalized Task) benchmark. However, it is not recommended as a pretraining reference. |
Malinowski in the Age of AI: Can large language models create a text game based on an anthropological classic? | A pipeline was developed to explore whether LLMs can independently generate text games based on anthropological classics. Although the book itself is unfamiliar, this study demonstrates a playful approach. Recently, there have been more projects that incorporate LLMs into interactive storytelling, such as Google’s "Unbounded: A Generative Infinite Game of Character Life Simulation." This direction holds appeal as LLMs can significantly enhance engagement and freedom in narrative-based games, like murder mystery and RPG scenarios. Traditional RPG setups often lacked sufficient "Dungeon Master" and other player interactions, leaving an unmet desire for personal adventure within unique story worlds. Compared to companion-type agents, the strength here lies in structured narratives that prevent repetitive dialogues and create engaging, evolving scenarios. |
What Factors Affect Multi-Modal In-Context Learning? An In-Depth Exploration | This work provides an ablation study on factors affecting multi-modal in-context learning (MM-ICL), particularly noting the impact of modality ordering on model performance. This issue was previously highlighted in the O1 multimodal pretraining proposal. Multimodal pretraining often employs either "paired" or "interleaved" formats for organizing image-text data, with the interleaved format leading to a sequence such as [Text][Image][Text][Text][Image][Image][Text] . Consequently, the model is less exposed to patterns involving multiple consecutive images followed by an instruction, as in [Image][Image][Image][Image][Instruction] . This potential mismatch in learned attention patterns could affect performance, although the trick was implemented in production without detailed ICP (input conditioning pattern) analysis. Applying ICP methods from textual contexts could be valuable here as well. |
MusicFlow: Cascaded Flow Matching for Text Guided Music Generation | Meta’s music generation model, MusicFlow, stands out as a relatively clean and straightforward approach to music generation, free from an overly complex layered structure commonly seen in similar models. The model compares MERT and HuBERT embeddings, finding HuBERT to be significantly stronger at the semantic level, thus opting for HuBERT. This choice, although somewhat disappointing, is understandable given HuBERT’s superior performance. Planning to listen to the generated music samples tomorrow. |
Deep Learning Based Dense Retrieval: A Comparative Study | This paper presents a comparative study of dense retrievers using datasets FiQA, HotpotQA, and Quora, specifically analyzing models like BERT, SimCSE, ANCE, Contriever, and DPR series. The robustness analysis under adversarial attacks appears to lack practical relevance, as the real-world applicability of such attacks remains unclear. ANCE stands out as the most effective across various conditions. Further clarification on the real-life scenarios for these adversarial cases would be valuable. |
Maintaining Informative Coherence: Migrating Hallucinations in Large Language Models via Absorbing Markov Chains | This paper utilizes absorbing Markov chains to quantify the importance of contextual information and measure information loss at different distances in generation. Although the benchmark results show modest improvements, the motivation addresses a genuine issue. The approach resembles the one in Professor He Junxian's recent work, Non-myopic Generation of Language Model for Reasoning and Planning, though this paper does not precisely target the "myopia" concept inherently related to neural text planning (NTP). Upon reflection, myopia in existing NTP and predictive encoding (PE) methods may not fully capture the hierarchical retrieval needed to support "one-to-many" relationships. This study prompts a rethinking on sentence construction as shaped by the loss weighting, where each dependency space angle learned in beam search remains narrow and "short-sighted." A potential evaluative approach for sentence continuity is to measure the probability of direct sequential prediction from sentence beginning to end relative to the search space distribution. By optimizing for an ideal loss based on this probability, and comparing it with the actual loss, biases in multi-task learning may become evident. This could be explored experimentally in the near term. |
MarDini: Masked Autoregressive Diffusion for Video Generation at Scale | This paper combines masked autoregressive models with diffusion models to achieve scalable video generation, aligning closely with recent implementations and trials in LLM directions. In this setup, the masked autoregressive model component manages the extractable planning signals, potentially corresponding to Chain-of-Thought (CoT) or semantic span information within continuous embeddings. The diffusion model uses the mask-predicted control signals to refine details, reconstructing high-resolution frames. This unified learning objective warrants further scrutiny. The modular organization across video and text generation intuitively relieves the model from needing to pinpoint logical or temporal dependencies within an overwhelming search space. With diffusion models’ noise and denoising mechanisms, this extensive Gaussian distribution search space does not lend itself well to imitation learning, particularly as the semantic meaning of this scale remains somewhat elusive. The Diffusion of Thought study similarly relies on explicit CoT as a temporal sequence within a consistency model framework. At present, it appears that the natural reconstruction, congruent with diffusion, should remain within the diffusion process, while planning and high-level sequence structure benefit from autoregressive masking. |
Uncertainty-Penalized Direct Preference Optimization | This paper introduces an uncertainty penalty to reduce overfitting in Direct Preference Optimization (DPO). By incorporating uncertainty-based regularization, it aims to mitigate the model's tendency to overfit during preference optimization, enhancing the generalization of learned preferences. |
Understanding Adam Requires Better Rotation Dependent Assumptions | This paper explores Adam optimizer’s sensitivity to rotations in parameter space. The analysis suggests a need for better rotation-dependent assumptions to understand Adam's behavior fully. Requires in-depth reading and analysis; marked for future review. |
MrT5: Dynamic Token Merging for Efficient Byte-level Language Models | This paper introduces a dynamic token merging mechanism in byte-level language models to accelerate processing without degrading model performance, significantly reducing inference runtime. Recent research has seen numerous approaches to handling different tokens, suggesting that this area has matured. It is recommended to follow up on this work, and there are plans to compile a reference list related to this topic over the weekend. |
ODRL: A Benchmark for Off-Dynamics Reinforcement Learning | This benchmark evaluates the ability of human-like RL agents to rapidly transfer strategies across structurally similar tasks, and the motivation behind it is considered very sensible. It is posited that the current approach of LLMs moving from NTP to SFT and then RLHF is essentially due to the infeasibility of directly scaling RL in the current language space size. There are insufficient signals, and the foundational models may not be robust enough, necessitating the use of imitation learning for cold starts. From an optimization perspective, the initial phase of NTP to SFT focuses on how to effectively imitate the target, while the latter aims to achieve a better verifier, enhancing robustness and general confidence in modeling the distribution of the positive space in the sampling space. Regarding scaling RL, the short-term focus is on leveraging the world knowledge within LLMs, while long-term research into cross-environment high-level strategy and experience generalization, akin to Google's research on Genie and Cross-Game DT, is deemed highly valuable. This belief is predicated on the understanding that efficiently generalizing highly abstract experiences and strategies learned in few-shot scenarios is instructive for scaling RL. Currently, the challenge lies in retaining highly abstract experience generalization, as there is scant research on pure strategy generalization across different Atari games. Much of the existing academic work on generalization focuses on recognizing highly abstract concepts within single games, rather than reaching the level of strategy generalization, leading to potential overclaims about generalization. It is recommended that more benchmarks like this be developed, without restricting them to robotic applications. |
SWE-Search: Enhancing Software Agents with Monte Carlo Tree Search and Iterative Refinement | This paper integrates Monte Carlo Tree Search (MCTS) into code agents, resulting in a notable performance increase. However, similar works have emerged recently, and the use of the UCT trick appears somewhat ad-hoc, possibly due to an inability to fully grasp the mathematical intent behind the formulas presented. The results seem largely experimental. Furthermore, the introduction of many uncontrollable factors, particularly in the evaluation phase, where it states that it “uses all relevant context including trajectory information, file context, and executed tests to provide a quantitative value estimation and qualitative explanation in natural language,” feels rather vague. The paper appears to be somewhat supportive of a peer's work. |
GPT-4o System Card | The paper does not capture many details, noting that the data organization only mentions "Web Data" and "Code and Math," which is an interesting point. In section 3.1, it appears that the red teaming efforts by OAI and Anthropic may be very intense and extreme, extending beyond just safety cases, which could lead to a qualitative change. However, effectively organizing a red team may involve various techniques. There was a tech blog referenced that raises questions about its credibility, available here: The Information Article. A minor detail in the evaluation section states, “We used Voice Engine to convert text inputs to audio, feed it to the GPT-4o, and score the outputs by the model. We always score only the textual content of the model output, except in cases where the audio needs to be evaluated directly, such as in evaluations for voice cloning.” The expression in section 5.3 seems to imply that their red teamers are also responsible for exploring broader potential scenarios for their models. Other sections feel somewhat vague, and further analysis may be warranted. |
HoPE: A Novel Positional Encoding Without Long-Term Decay for Enhanced Context Awareness and Extrapolation | Proposed by Xiaomi, this paper introduces a new positional encoding method. It suggests that the attention pattern exhibits a U-shaped curve and analyzes specific components of RoPE, termed "activation components," which significantly impact the attention learned during the early training phases. The authors argue that low-frequency components are ineffective for representing positional information, advocating for a method that only utilizes high-frequency components. The actual effectiveness of this approach remains to be verified. Further exploration is planned for tomorrow, and a forward is sent to @单勇, as the intuitive mathematical implications of the "activation components" definition are not fully grasped yet. |
LLMs Can Evolve Continually on Modality for X-Modal Reasoning | This paper presents Huawei's Any2Any model, which integrates single-modality adapters in parallel during the pre-training of a Q-Former. This approach is designed to effectively adapt to new modalities while allowing the adapters to be frozen post-training. The benchmark they established for evaluating continual learning in multimodal settings appears meaningful. Their main selling point is the claim that adding an audio modality to a text-image model can be done without retraining the existing text-image components. While this claim has practical implications, the proposed solution comes across as somewhat convoluted. |
AutoBench-V: Can Large Vision-Language Models Benchmark Themselves? | This paper explores the concept of having multi-modal large language models (MLLMs) autonomously design evaluation hierarchies and generate questions based on user-defined assessment goals to benchmark other MLLMs. This approach facilitates the creation of a more user-centric Visual Question Answering (VQA) benchmark, which is a valuable perspective given the current scarcity of high-quality MLLM benchmarks. |
LARP: Tokenizing Videos with a Learned Autoregressive Generative Prior | This paper proposes using an autoregressive generative prior model to act as a video tokenizer, aiming to remove redundant information from video data. The core intuition suggests that if a suitable function ( f ) representing the learned consistency model can be identified and combined with keyframes, it could serve as an effective tokenizer for multi-modal large language models (MLLMs). Theoretically, for individual images (or multi-image contexts), this function ( f ) represents reconstruction, while for video, the objective is to capture a form of semantic consistency that is learned across frames. This exploration could lead to innovative approaches in video processing using diffusion models, although further refinement of this idea is needed. |
AutoKaggle: A Multi-Agent Framework for Autonomous Data Science Competitions | This framework is specifically designed for tabular Kaggle competitions and involves a detailed multi-agent workflow. The process consists of five main steps: understanding the data and planning, cleaning the data, employing a retrieval-augmented generation (RAG) approach to plan specific libraries for each step, feature engineering, and modeling. The framework allows for flexibility and control by specifying external libraries for feature engineering and model fitting, enabling the integration of new libraries. The authors chose a smaller scenario, coinciding with MLE-Bench, which showcases their worldview on the practical application of multi-agent systems. By focusing on a domain-specific approach, they aim to reflect a realistic workflow while maintaining extensibility, ensuring that unnecessary tasks are decoupled from the model's responsibilities. This allows for clean models to make decisions and handle redundant work without overburdening them with inappropriate tasks. Notably, their framework has shown better submission rates and results in tabular settings compared to AIDE, though it may be overly detailed for some contexts. Using a more streamlined model, like o1-mini, resulted in excess noise from unnecessary context, impacting performance. This indicates that o1 has indeed learned a valuable lesson about agent functionalities. Interestingly, AIDE's approach seems simpler, raising questions about its underlying assumptions regarding model strength. |
Diff-Instruct* : Towards Human-Preferred One-step Text-to-image Generative Models |
This paper discusses a diffusion model for text-to-image generation developed by Xiaohongshu. It appears to focus on enhancing human preference in the generative process, likely proposing improvements over existing models to align better with user expectations and aesthetic qualities. It will be interesting to delve into their methodology and findings to understand how they achieve this goal and what differentiates their approach from other models in the field. I'll mark this for further review. |
Cooperative Strategic Planning Enhances Reasoning Capabilities in Large Language Models | This paper explores enhancing reasoning capabilities in LLMs through cooperative strategic planning by breaking down reasoning patterns. The approach aligns well with our work on the Comparative Study on O1. The identified reasoning types—Deductive, Inductive, Abductive, Analogical Reasoning, and Contradiction—along with strategies such as Decomposition, Enumeration, Elimination, and Reflection, provide a comprehensive framework for analyzing reasoning processes in LLMs. It would be beneficial to examine how these strategies are operationalized in their experiments and whether they lead to significant improvements in reasoning performance. I'll keep this in mind for further investigation. |

Bongard in Wonderland: Visual Puzzles that Still Make AI Go Mad? | The paper presents a concise yet sophisticated Visual Language Model (VLM) test set. While Bongard problems fundamentally focus on identifying graphical classification criteria, their rule patterns primarily rely on image-based pattern recognition features. These features, while not overtly complex, present meaningful challenges even for human subjects. A distinctive characteristic emerges from its relatively modest visual information density: this property circumvents typical vision encoder limitations, enabling effective evaluation of the encoder's global conceptual understanding capabilities. This aligns particularly well with the general optimization objectives of CLIP-like encoders, making the benchmark particularly valuable for assessing vision encoder training quality. |
ReasonAgain: Using Extractable Symbolic Programs to Evaluate Mathematical Reasoning | The paper presents an intuitive and well-structured approach: extracting fixed static reasoning templates from mathematical problems to evaluate model robustness. Rather than optimizing for specific benchmarks like GSM8k or MATH, the methodology generates additional effective samples through template utilization, representing a more systematic approach. A recent proposal suggests extending this methodology to data augmentation, particularly relevant for competitive programming problems (e.g., LeetCode). Given the finite set of problem templates (e.g., knapsack, greedy algorithms, dynamic programming), the approach becomes viable when four conditions are met: 1. Establishment of root templates; 2. Robust template expansion capability for incorporating new elements. 3. Stable prompt transformation mechanisms for template-to-problem conversion. 4. Fixed brute-force algorithms for template-based solution generation. This framework enables generation of apparently out-of-distribution problems while maintaining consistent solution methodologies. The approach appears particularly promising for competitive programming training data generation. Mathematical problems, especially high-school examination problems, present even more straightforward opportunities for template extraction and application. |

Counting Ability of Large Language Models and Tokenization | This theoretical paper presents three key findings: 1. In theory, RNNs and LSTMs can execute dynamic counting through maintenance of independent counters, while Transformers are constrained to TC0 complexity level. 2. Chain of Thought (CoT) reasoning combined with ideal assumptions enables complete counting capabilities. 3. The combination of imperfect tokenization with CoT performs below theoretical CoT limits, though it appears questionable whether tokenization represents the primary bottleneck in achieving CoT's theoretical maximum performance. |
CloserMusicDB: A Modern Multipurpose Dataset of High Quality Music | The research presents a potentially valuable cold-start dataset featuring diverse music label annotations. |
Brain-like Functional Organization within Large Language Models | While the paper presents speculative conclusions and methodology requiring further validation, it introduces an intriguing research approach: extracting patterns from LLMs as fixed regressor feature initializations for brain activity prediction. The study demonstrates coupling between these features and specific functional brain networks using a designated dataset. Despite the limited dataset scope, the methodological framework appears theoretically sound. The approach potentially enables identification of functional brain networks not represented in current LLMs, suggesting opportunities for targeted model enhancement. |
Scaling Law with Learning Rate Annealing | The research incorporates annealing effects into Scaling Law modeling. Initial examination of the formulation suggests potential theoretical limitations, particularly regarding the lack of comprehensive analysis of annealing's impact on loss functions. This inadequate theoretical foundation may indicate incomplete consideration of these effects in the mathematical modeling. |
Stick-breaking Attention | The research, authored by Yikang Shen, presents a theoretically elegant approach: implementing attention through a stick-breaking process where, for each token in a sequence, the model determines the proportion of remaining attention (the 'stick') to allocate, continuing until complete allocation is achieved. This methodology demonstrates two significant advantages over the conventional softmax+RoPE approach: 1. The theoretical framework enables learning of hierarchical paragraph information, avoiding the unnatural point-to-multipoint relationships inherent in RoPE. 2. The sequential allocation mechanism introduces an ingeniously designed ordering constraint. 3. The mathematical formulation warrants further analysis. |

Key findings indicate that while zero activation of features proves ineffective, negative scaling is necessary for unlearning. However, this negative scaling approach introduces comparable or increased side effects in unrelated multiple-choice tasks. While the methodology lacks robustness, potentially due to suboptimal feature processing, the intuition behind the approach merits consideration. |
