About Me

Hi! I’m Zitai Wang (王子泰, E-mail: wangzitai@iie.ac.cn). Now I am a PhD. student of Institute of Information Engineering, Chinese Academy of Sciences (IIE, CAS), supervised by Prof. Qingming Huang (黄庆明) (IEEE Fellow). I am also lucky to have opportunities to collaborate with Qianqian Xu (许倩倩) (Professor at ICT, CAS.), Xiaochun Cao (操晓春) (Professor at Sun Yat-sen University, Shenzhen Compus), Yuan He (何源) (Alibaba Group), Zhiyong Yang (杨智勇) (postdoc at UCAS), Ke Ma (马坷) (Assistant Professor at UCAS), and Yangbangyan Jiang (姜阳邦彦) (postdoc at UCAS).

My research interest includes machine learning and data mining. I have authored or co-authored several academic papers in top-tier international conferences and journals, including T-PAMI, NeurIPS, and ACM Multimedia.
