Cross-Domain Energy-Guided Diffusion Generation for Off-Dynamics Reinforcement Learning

Yu Yang, Yihong Guo, Anqi Liu +1

Off-dynamics offline reinforcement learning seeks to learn a target-domain policy from a large source dataset and a limited target dataset under mismatched transition dynamics. Exi…

Distributionally Robust Policy Evaluation under General Covariate Shift in Contextual Bandits

Yihong Guo, Hao Liu, Yisong Yue +1

We introduce a distributionally robust approach that enhances the reliability of offline policy evaluation in contextual bandits under general covariate shifts. Our method aims to…
