Two papers on RL, COREP and PAR, were accepted at ICML’24, and one paper about RL with natural language action space, MIPO, was accepted at ACL’24

Two papers about fine-tuning LLMs for decision-making tasks, AdaRefiner and LLaMA-Rider, were accepted at NAACL’24.

Three papers respectively on LMMs, policy pre-training and offline RL were accepted at ICLR’24. Additionally, we have one paper accepted at TMLR, two at AAAI’24, and two at AAMAS’24. Congratulations to all.

Recently developed foundation models, such as large language models and multi-modal models, open great opportunities to build generally capable agents, combined with reinforcement learning. This project focuses on learning skills and foundation models and connecting them to build generalist agents. In the following, we introduce some of our studies. For more details, please refer to the papers. Plan4MC We study building a multi-task agent in Minecraft. Without human demonstrations, solving long-horizon tasks in this open-ended environment with reinforcement learning (RL) is extremely sample inefficient. [Read More…]


Multi-Agent Reinforcement Learning (MARL) has recently attracted much attention from the communities of machine learning, artificial intelligence, and multi-agent systems. As an interdisciplinary research field, there are so many unsolved problems, from cooperation to competition, from agent communication to agent modeling, from centralized learning to decentralized learning. MARL has been the main research focus of our lab. We are investigating the field from many perspectives. In the following, we introduce some of our studies. [Read More…]
