Trajectory Data Suffices for Statistically Efficient Policy Evaluation in Fixed-Horizon Offline RL with Linear qπ-Realizability and Concentrability

Volodymyr Tkachuk, Csaba Szepesvári, Xiaoqi Tan

We study finite-horizon offline reinforcement learning (RL) with function approximation for both policy evaluation and policy optimization. Prior work established that statisticall…

Trajectory Data Suffices for Statistically Efficient Learning in Offline RL with Linear qπ-Realizability and Concentrability

Volodymyr Tkachuk, Gellért Weisz, Csaba Szepesvári

We consider offline reinforcement learning (RL) in H-horizon Markov decision processes (MDPs) under the linear qπ-realizability assumption, where the action-value function of…

Regret Minimization via Saddle Point Optimization

Johannes Kirschner, Seyed Alireza Bakhtiari, Kushagra Chandak +2

A long line of works characterizes the sample complexity of regret minimization in sequential decision-making by min-max programs. In the corresponding saddle-point game, the min-p…
