The recent developments in the field of large language models (LLMs) have shown a significant shift towards enhancing self-improvement and reasoning capabilities. Researchers are increasingly focusing on methods that allow LLMs to refine their own performance without heavy reliance on human supervision. This includes strategies such as guided self-improvement, which aims to balance the sampling of challenging tasks to prevent performance plateaus. Additionally, there is a growing emphasis on optimizing the training data order to better mimic the discovery process of proofs, which has shown to improve the performance of LLMs in theorem proving tasks. Another notable trend is the integration of reinforcement learning techniques to enhance the step-wise reasoning and policy optimization of LLMs, addressing the limitations of sparse rewards in traditional methods. Furthermore, the concept of self-consistency preference optimization is being explored to iteratively train models on consistent answers, leading to substantial improvements in reasoning tasks. Lastly, the idea of meta-reasoning is being leveraged to improve tool use in LLMs, suggesting a promising direction for enhancing their generalization abilities in complex tasks.

Noteworthy papers include one that introduces a Socratic-guided sampling method to improve LLM self-improvement efficiency, and another that proposes a novel training order for proof generation, significantly enhancing proof success rates.
