Zeyi Liu's Homepage

Welcome to my personal homepage👋

I am currently a Ph.D. candidate in the Department of Automation at Tsinghua University, with Prof. Xiao He and Prof. Donghua Zhou at the Research Center of Safety Control Technology. Prior to that, I received my B.E. degree from Southwest University, majoring in computer science and technology. During that time, I served as a research assistant in the Laboratory of Information Fusion and Intelligent Science, led by Prof. Yong Deng.

My research interests include online learning and its applications in multi-mode fault diagnosis and real-time safety assessment of dynamic systems. Currently, I focus on applying stream learning techniques under constrained annotations to the complex dynamic systems in industrial processes.
