Yu Zhang

Hi, my name is Yu Zhang ([jy tʃɑŋ], 張宇/张宇 in traditional/simplified Chinese). I am a second-year PhD student at HLT@SUDA, co-advised by Prof. Guohong Fu and Prof. Zhenghua Li (expected to graduate in 2024). Before this, I received my M. Eng. degree from Soochow University in 2021. My main research interest focuses on structured prediction and latent variable models.
