Yusuke Matsui

Lecturer (Assistant Professor)

Department of Information and Communication Engineering, Graduate School of Information Science and Technology, The University of Tokyo, Japan

I am a Lecturer (Assistant Professor) at the University of Tokyo, Japan. My main research areas are computer vision, data structures, and machine learning. I specialize in two areas: (1) developing algorithms and systems for large-scale data indexing and (2) creating learning-enhanced data structures that combine machine learning with traditional data structures.
