Non-asymptotic Confidence Intervals of Off-policy Evaluation: Primal and Dual Bounds

ICLR 2021poster

Off-policy evaluation (OPE) is the task of estimating the expected reward of a given policy based on offline data previously collected under different policies. Therefore, OPE is a key step in applying reinforcement learning to real-world domains such as medical treatment, where interactive data col…
