Chung-En Tsai (蔡仲恩)

Hi! My name is Chung-En. I'm a research assistant in computer science at National Taiwan University. I am fortunate to be advised by Prof. Yen-Huan Li and to collaborate with Prof. Hao-Chung Cheng. Previously, I have worked with Prof. Chun-Hsiung Hsia and Prof. Kai-Min Chung. I received my bachelor's degree in computer science from National Taiwan University in 2023.

I will start my direct doctorate in computer science at ETH Zürich this September.

Research

I am interested in the theories of learning, optimization, and complex systems. I am currently working in online learning and large-scale optimization with logarithmic loss.
