Offline Reinforcement Learning with OOD State Correction and OOD Action Suppression

Yixiu Mao, Qi Wang, Chen Chen +2

In offline reinforcement learning (RL), addressing the out-of-distribution (OOD) action issue has been a focus, but we argue that there exists an OOD state issue that also impairs…
