About Me
Hi! I’m Yang Liu (柳洋, E-mail: liuyang232@mails.ucas.ac.cn). Now I am a PhD. student of School of Computer Science and Technology, University of Chinese Academy of Sciences (SCST, UCAS), supervised by Prof. Qingming Huang (黄庆明) (IEEE Fellow) and Qianqian Xu (许倩倩) (Professor at ICT, CAS). I have received the B.E. degree in Software Engineering from HIT in 2023. My research interest includes self-supervised learning, video understanding, and computer vision.
