arXiv:2606.06475v1 Announce Type: new Abstract: Recent advancements in reasoning language models have been driven by Reinforcement Learning (RL) fine-tuning. Most often, these rely on the Group Relative Policy Optimization (GRPO) algorithm or modifications thereof to steer the models to produce Chain-of-Thought (CoT) traces. The final answer can only be verified, and the reward assigned, after the CoT trace is complete, making it a delayed reward problem. GRPO and its modifications correspond to Monte Carlo methods in standard RL, which are known to suffer from high variance. A possible soluti
The continuous drive for more effective and stable training methods in large language models, particularly those using reinforcement learning, necessitates innovations like RREDCoT to overcome existing limitations such as high variance in reward assignment.
This research addresses a core technical challenge in Reinforcement Learning from Human Feedback (RLHF), which is crucial for advancing the capabilities and reliability of reasoning language models, impacting the efficiency and efficacy of AI agents.
The proposed RREDCoT method offers a more granular and stable way to assign rewards during the training of reasoning models, potentially leading to more robust and accurate Chain-of-Thought (CoT) traces and overall improved model performance.
