Yiyun Zhou (周逸云)

Second-year master in Zhejiang University.

👋 Hi! I am Yiyun Zhou (周逸云 in Chinese), a second-year master’s student in Zhejiang University and advised by Prof. Jingyuan Chen.

🔬 My research has centered on the data miming, multimodal learning, and LLM. I have published some papers on the above topics at the top-tier international AI conferences such as WWW2025, KDD2025, ACL2025 and ECML-PKDD2025. Recently, I devote myself to the development of multi-view multi-label learning.

I will graduate in 2026 and am currently seeking PhD opportunities for fall admission. Feel free to contact me at yiyunzhou@zju.edu.cn.
