Bringing Value Models Back: Generative Critics for Value Modeling in LLM Reinforcement Learning

Zikang Shan, Han Zhong, Liwei Wang +1

Credit assignment is a central challenge in reinforcement learning (RL). Classical actor-critic methods address this challenge through fine-grained advantage estimation based on a…

DPO Meets PPO: Reinforced Token Optimization for RLHF

Han Zhong, Zikang Shan, Guhao Feng +6

In the classical Reinforcement Learning from Human Feedback (RLHF) framework, Proximal Policy Optimization (PPO) is employed to learn from sparse, sentence-level rewards -- a chall…

Rethinking Model-based, Policy-based, and Value-based Reinforcement Learning via the Lens of Representation Complexity

Guhao Feng, Han Zhong

Reinforcement Learning (RL) encompasses diverse paradigms, including model-based RL, policy-based RL, and value-based RL, each tailored to approximate the model, optimal policy, an…
