Scalable Multi-Agent Reinforcement Learning with General Utilities

no code implementations15 Feb 2023 Donghao Ying, Yuhao Ding, Alec Koppel, Javad Lavaei

The objective is to find a localized policy that maximizes the average of the team's local utility functions without the full observability of each agent in the team.

Policy-based Primal-Dual Methods for Concave CMDP with Variance Reduction

1 code implementation22 May 2022 Donghao Ying, Mengzi Amy Guo, Hyunin Lee, Yuhao Ding, Javad Lavaei, Zuo-Jun Max Shen

In the exact setting, we prove an $O(T^{-1/3})$ convergence rate for both the average optimality gap and constraint violation, which further improves to $O(T^{-1/2})$ under strong concavity of the objective in the occupancy measure.

A Dual Approach to Constrained Markov Decision Processes with Entropy Regularization

no code implementations17 Oct 2021 Donghao Ying, Yuhao Ding, Javad Lavaei

We study entropy-regularized constrained Markov decision processes (CMDPs) under the soft-max parameterization, in which an agent aims to maximize the entropy-regularized value function while satisfying constraints on the expected total utility.
