DVPO: Distributional Value Modeling-based Policy Optimization for LLM Post-Training

Dingwei Zhu, Zhiheng Xi, Shihan Dou +15

Reinforcement learning (RL) has shown strong performance in LLM post-training, but real-world deployment often involves noisy or incomplete supervision. In such settings, complex a…
