Sule Bai | 白苏乐 Hi! I'm a third-year master student in Tsinghua University (Shenzhen International Graduate School), supervised by Prof. Yansong Tang. Before that, I received my bachelor's degree from the School of Computer Science in the Beijing University of Posts and Telecommunications in 2023. My currect research interest lies in Multimodal LLM and its applications.
