Researchers have developed a new framework for recovering reward functions in competitive games, specifically two-player zero-sum matrix games and Markov games. This approach uses entropy regularization to address challenges like ambiguity and non-unique solutions in inverse problems. The proposed algorithm, which can incorporate methods like Maximum Likelihood Estimation, offers theoretical guarantees for reliability and sample efficiency, and has demonstrated practical effectiveness in numerical studies.
