π€ About me
I am a Ph.D. student at the Institute for Artificial Intelligence, Peking University. I am working under the supervision of Prof. Yaodong Yang, my first initiation mentor in multi-agent systems. My research interests include reinforcement learning, game theory, and their intersection with fundamental science. The current topics I am focused on are:
- Multi-agent Learning: Developing practical algorithms for large-scale system control and multi-player computer games.
- Reinforcement Learning for Science: Exploring the potential of reinforcement learning in fundamental scientific problems.
