Variance-Reduced Q-Learning over Static and Time-Varying Networks

Sreejeet Maity, Feng Zhu, Aritra Mitra, Robert W. Heath

We investigate a decentralized reinforcement learning problem involving multiple agents that interact with the same Markov Decision Process (MDP). The agents can exchange information over a network to collectively learn the optimal state-action value function. For this setting, w…

Robust Asynchronous Q-Learning under Reward and State Corruption via Batching

Sreejeet Maity, Aritra Mitra

Motivated by reinforcement learning in harsh environments, we consider the problem of learning an optimal policy subject to adversarially corrupted feedback. Specifically, at each time-step, an adversary can perturb both the reward and state observations of the learner following…
