arXiv:2602.07832v2 Announce Type: replace Abstract: Process rewards have been widely used in deep reinforcement learning to improve training efficiency, reduce variance, and prevent reward hacking. In LLM reasoning, existing works also explore various solutions for learning effective process reward models (PRM) with or without the help of an expert policy. However, existing methods either rely on strong assumptions about the expert policies (e.g., requiring their reward functions) or suffer intrinsic limitations (e.g., entropy collapse), resulting in weak PRMs or limited generalizability.

The continuous evolution of LLM reasoning requires more efficient and robust methods for learning process reward models, addressing limitations of current inverse reinforcement learning approaches.
Improved methods for training LLMs through inverse reinforcement learning enhance their reasoning capabilities, leading to more sophisticated and reliable AI agents.
This research offers a novel approach to learning effective process reward models for LLMs, potentially leading to more generalizable and less assumption-dependent AI training.
