Federated Q-Learning: Linear Regret Speedup with Low Communication Cost

no code implementations22 Dec 2023 Zhong Zheng, Fengyu Gao, Lingzhou Xue, Jing Yang

In this paper, we consider federated reinforcement learning for tabular episodic Markov Decision Processes (MDP) where, under the coordination of a central server, multiple agents collaboratively explore the environment and learn an optimal policy without sharing their raw data.
