Supported Value Regularization for Offline Reinforcement Learning

Yixiu Mao (Tsinghua University), Xiangyang Ji (Tsinghua University)

Reinforcement Learning

🎯 What it does: A Support Value Regularization (SVR) method is proposed, which penalizes the Q-values of out-of-distribution (OOD) actions that exceed the support of the behavior dataset in offline reinforcement learning, while retaining the standard Bellman update in the in-distribution (ID) region, thus addressing the issues of overestimation and extrapolation error.
