Xiao Liu

Hi, my name is Xiao Liu (刘潇). I am a graduate student in Computer Science at Tsinghua University, supervised by Prof. Jie Tang. My major research interests include machine learning, knowledge graphs and data mining.

Currently I am seeking for approaches to construct large-scale knowledge graphs in an unsupervised or self-supervised fashion (i.e., without human supervision). Constructing knowledge graphs have been a central challenge for decades in my field, and thanks to the boosting pre-trained models and self-supervised learning, this goal could be achieved soon.
