Momentum for the Win: Collaborative Federated Reinforcement Learning across Heterogeneous Environments

no code implementations29 May 2024 Han Wang, Sihong He, Zhili Zhang, Fei Miao, James Anderson

In contrast to existing results, we demonstrate that both FedSVRPG-M and FedHAPG-M, both of which leverage momentum mechanisms, can exactly converge to a stationary point of the average performance function, regardless of the magnitude of environment heterogeneity.

Robust Electric Vehicle Balancing of Autonomous Mobility-On-Demand System: A Multi-Agent Reinforcement Learning Approach

no code implementations30 Jul 2023 Sihong He, Shuo Han, Fei Miao

In this work, we design a multi-agent reinforcement learning (MARL)-based framework for EAVs balancing in E-AMoD systems, with adversarial agents to model both the EAVs supply and mobility demand uncertainties that may undermine the vehicle balancing solutions.
