New minimax PAC bounds for learning in exogenous contextual MDPs

Researchers have developed new minimax PAC bounds for learning in exogenous contextual Markov decision processes (MDPs). The study focuses on tabular discounted MDPs with exogenous, i.i.d. contexts that can influence rewards and transitions. The proposed algorithms offer improved sample complexity for policy evaluation, best-value estimation, and best-policy extraction, with rates that are independent of the context space size and are minimax optimal.
