Biography

I am a PhD student in the Department of Computer Science and Technology at Tsinghua University. I am also a member of the Knowledge Engineering Group, advised by Prof. Jie Tang.

My research interest lies in the application of machine learning algorithms to real-world systems, including information retrieval [ECML/PKDD'18,KDD'19,TKDE,SIGIR'19], knowledge graphs [TKDE], and pretrained language models[arxiv,arxiv]. Generally, I am also interested in the algorithms for machine learning and reinforcement learning.

In my spare time, I like to read science fiction novels and history books, especially the history of Ancient Rome and Three Kingdoms Period in China.
