LLM Self-Improvement Training: Can LLMs Learn to Get Better at Getting Better?

This paper introduces Exploratory Iteration (EXIT), a family of reinforcement learning methods to train LLMs to self-improve. EXIT trains LLMs on single-step self-improvement tasks to improve their performance on multi-step self-improvement at inference time. The authors demonstrate EXIT's effectiveness in competition math, multi-turn tool use, and machine learning engineering tasks.

Possible Conflicts of Interest

The authors are affiliated with Meta Superintelligence Labs and University of Oxford, which might influence the research direction and resource allocation. However, no direct financial conflicts related to the presented work were identified.

Identified Weaknesses

Limited Evaluation Domains

While the chosen domains are relevant, evaluating EXIT on a broader range of tasks would strengthen the conclusions. More complex real-world applications with richer feedback mechanisms would better demonstrate the generalizability of the approach.

Comparison to Other Self-Improvement Methods

A more comprehensive comparison to other state-of-the-art self-improvement techniques is needed to position EXIT's contributions effectively. It's unclear if EXIT is truly outperforming existing methods or offering a novel perspective on the same problem.

Clarity on Exploration Mechanisms

The paper mentions exploration mechanisms like self-divergence and a diversity bonus, but the practical implementation and impact are not thoroughly explored. More detailed analysis and ablation studies could clarify their individual contributions.

Computational Cost

Although EXIT aims to improve efficiency compared to naive k-step training, the paper lacks analysis on the computational costs of EXIT itself. A discussion of the training time, memory requirements, and inference latency would provide valuable insights into its scalability.

Rating Explanation

The paper presents a novel approach to LLM self-improvement with promising results in several domains. The proposed EXIT method demonstrates potential to efficiently train LLMs for improved self-correction capabilities at inference time. However, several limitations regarding evaluation domains, comparisons to related work, and clarity on certain aspects prevent a higher rating.
