Learning to Reason with Insight for Informal Theorem Proving

arXiv:2604.16278v2 Announce Type: replace-cross Abstract: Although most of the automated theorem-proving approaches depend on formal proof systems, informal theorem proving can align better with large language models' (LLMs) strength in natural language processing. In this work, we identify a primary bottleneck in informal theorem proving as a lack of insight, namely the difficulty of recognizing the core techniques required to solve complex problems. To address this, we propose $\texttt{DeepInsight}$, a unified training framework designed to cultivate this essential reasoning skill and enable

Why this matters
Why now

The increasing capabilities of Large Language Models (LLMs) are pushing researchers to address their fundamental limitations, such as complex reasoning and insight, to unlock more advanced applications.

Why it’s important

Improving LLMs' ability to reason with insight for informal theorem proving addresses a core cognitive bottleneck, potentially accelerating the development of more intelligent and autonomous AI systems.

What changes

This research introduces a framework that could significantly enhance LLMs' problem-solving capabilities beyond pattern matching, enabling them to tackle more abstract and complex logical tasks.

Second-order effects
Direct

LLMs gain a more robust capacity for complex logical reasoning and problem identification, moving beyond superficial textual understanding.

Second

The development of highly autonomous AI agents capable of tackling previously intractable intellectual problems could accelerate, impacting various white-collar professions.

Third

This breakthrough could lead to the discovery of novel solutions in scientific research and engineering, as AI systems are able to reason about and solve complex problems with less overt human guidance.
