Inverse Q-Learning Done Right: Offline Imitation Learning in -Realizable MDPs
Antoine Moulin, Gergely Neu, Luca Viano
We study the problem of offline imitation learning in Markov decision processes (MDPs), where the goal is to learn a well-performing policy given a dataset of state-action pairs ge…
