• Oct. 2023: We have released “Data-Driven Control Library (D2C)”, which provides an easy-to-use and comprehensive library for real-world data-driven control & decision-making problems! Project page available at https://github.com/AIR-DI/D2C.

• Sep. 2023: We have released “OpenChat: Advancing Open-source Language Models with Mixed-Quality Data”, which uses ideas from offline RL to fine-tune open-source large language models! Project page available at https://github.com/imoneoi/openchat.

• Sep. 2023: Our two recent papers “Look Beneath the Surface: Exploiting Fundamental Symmetry for Sample-Efficient Offline RL” and “Offline Multi-Agent Reinforcement Learning with Implicit Global-to-Local Value Regularization” have been accepted in NeurIPS 2023!

• Jan. 2023: Our three recent papers “Offline RL with No OOD Actions: In-Sample Learning via Implicit Value Regularization”, “When Data Geometry Meets Deep Function: Generalizing Offline Reinforcement Learning” and “Mind the Gap: Offline Policy Optimization for Imperfect Rewards” have been accepted in ICLR 2023!

🔥 We are hiring: we are looking for postdocs and student interns. If you are interested in the research directions of data-driven decision-making, please feel free to contact us!
