1). Grandmaster-Level Chess Without Search - trains a 270M parameter transformer model with supervised learning on a dataset of 10 million chess games with up to 15 billion data points; reaches a Lichess blitz Elo of 2895 against humans, and solves a series of challenging chess puzzles; it shows the potential of training at scale for chess and without the need for any domain-specific tweaks or explicit search algorithms.

2). AnyTool - an LLM-based agent that can utilize 16K APIs from Rapid API; proposes a simple framework consisting of 1) a hierarchical API-retriever to identify relevant API candidates to a query, 2) a solver to resolve user queries, and 3) a self-reflection mechanism to reactivate AnyTool if the initial solution is impracticable; this tool leverages the function calling capability of GPT-4 so no further training is needed; the hierarchical API-retriever is inspired by a divide-and-conquer approach to help reduce the search scope of the agents which leads to overcoming limitations around context length in LLMs; the self-reflection component helps with resolving easy and complex queries efficiently.

3). A Phase Transition between Positional and Semantic Learning in a Solvable Model of Dot-Product Attention - investigates and expands the theoretical understanding of learning with attention layers by exploring the interplay between positional and semantic attention; it employs a toy model of dot-product attention and identifies an emergent phase transition between semantic and positional learning; shows that if provided with sufficient data, dot-product attention layer outperforms a linear positional baseline when using the semantic mechanism.

4). Indirect Reasoning with LLMs - proposes an indirect reasoning method to strengthen the reasoning power of LLMs; it employs the logic of contrapositives and contradictions to tackle IR tasks such as factual reasoning and mathematic proof; it consists of two key steps: 1) enhance the comprehensibility of LLMs by augmenting data and rules (i.e., the logical equivalence of contrapositive), and 2) design prompt templates to stimulate LLMs to implement indirect reasoning based on proof by contradiction; experiments on LLMs like GPT-3.5-turbo and Gemini Pro show that the proposed method enhances the overall accuracy of factual reasoning by 27.33% and mathematic proof by 31.43% compared to traditional direct reasoning methods.

5). ALOHA 2 - a low-cost system for bimanual teleoperation that improves the performance, user-friendliness, and durability of ALOHA; efforts include hardware improvements such as grippers and gravity compensation with a higher quality simulation model; this potentially enables large-scale data collection on more complex tasks to help advanced research in robot learning.

6). More Agents is All You Need - presents a study on the scaling property of raw agents instantiated by LLMs; finds that performance scales when increasing agents by simply using a sampling-and-voting method. (paper | tweet)
7). Self-Discovered Reasoning Structures - proposes a new framework, Self-Discover, that enables LLMs to select from multiple reasoning techniques (e.g., critical thinking and thinking step-by-step) to compose task-specific reasoning strategies; outperforms CoT (applied to GPT-4 and PaLM 2) on BigBench-Hard experiments and requires 10-40x fewer inference compute than other inference-intensive methods such as CoT-Self-Consistency; the self-discovered reasoning structures are also reported to transfer well between LLMs and small language models (SLMs).

8). DeepSeekMath - continues pretraining a code base model with 120B math-related tokens; introduces GRPO (a variant to PPO) to enhance mathematical reasoning and reduce training resources via a memory usage optimization scheme; DeepSeekMath 7B achieves 51.7% on MATH which approaches the performance level of Gemini-Ultra (53.2%) and GPT-4 (52.9%); when self-consistency is used the performance improves to 60.9%.

9). LLMs for Table Processing - provides an overview of LLMs for table processing, including methods, benchmarks, prompting techniques, and much more. (paper | tweet)
10). LLM-based Multi-Agents - discusses the essential aspects of LLM-based multi-agent systems; it includes a summary of recent applications for problem-solving and word simulation; it also discusses datasets, benchmarks, challenges, and future opportunities to encourage further research and development from researchers and practitioners.
