About
Hello! I am a final year student of Yao Class at IIIS, Tsinghua University. I will join Carnegie Mellon University (CMU) as a Ph.D. student in Electrical and Computer Engineering (ECE), starting from Fall 2024.
My research passion lies in designing scalable and efficient algorithms for practical machine learning systems. For this aim, I am interested in a broad spectrum of topics, including but not limited to large language models, distributed machine learning and reinforcement learning. During my undergraduate studies, I focused on reinforcement learning, developing algorithms that integrate rigorous theoretical foundations with real-world practicality.
I am open to collaborations. If you have any ideas which we both might be interested in, please feel free to reach out!
Selected Research
Model-based return-conditioned supervised learning
Research intern at UW (Feb. 2023 - Aug. 2023).
Supervisor: Simon S. Du.
We proposed model-based return-conditioned supervised learning (MBRCSL), a novel offline RL framework that is able to do trajectory stitching while retaining the strength of return-conditioned supervised learning (RCSL) to avoid Bellman completeness requirements. [website]
Networked Markov Potential Games
Remote research intern at Caltech (Feb. 2022 - Feb. 2023).
Supervisor: Adam Wierman.
We proposed networked Markov potential games (NMPG) as a more practical relaxation of Markov potential games (MPG), and designed a localized actor-critic algorithm with provable finite-sample bound. [arXiv]
