Ziquan Liu

About

Hi, I am Ziquan Liu, a 5th year PhD student of computer science at City University of Hong Kong in Video, Image, and Sound Analysis Lab. My research interest is machine learning, including of deep learning and its mathematical interpretation, statistical learning and efficient training and inference. I was born and raised in Anhui province of China. I obtained my Bachelor of Engineering in Information Engineering from Beihang University and secondary Bachelor of Science in Mathematics from the same university, both in 2017.
