Plan Better Amid Conservatism: Offline Multi-Agent Reinforcement Learning with Actor Rectification [article]

Ling Pan, Longbo Huang, Tengyu Ma, Huazhe Xu
2022 arXiv   pre-print
Following this intuition, we propose a simple yet effective method, Offline Multi-Agent RL with Actor Rectification (OMAR), which combines the first-order policy gradients and zeroth-order optimization  ...  Given the recent success of transferring online RL algorithms to the multi-agent setting, one may expect that offline RL algorithms will also transfer to multi-agent settings directly.  ...  We compare OMAR against state-of-the-art offline RL methods including CQL and TD3+BC [Fujimoto and Gu, 2021] . We also compare it with a recent offline MARL algorithm MA-ICQ [Yang et al., 2021] .  ...
