Bio
Xiang Li is currently a research professor and also Ph.D. advisor in the School of Data Science and Engineering at East China Normal University, leading the PLANING lab (graPh mining and LANguage processING ☺). Before that, he received his Ph.D. degree from The University of Hong Kong in 2018,
M.Eng. degree from University of Science and Technology of China in 2014 and B.Eng. degree from Nanchang University in 2011, respectively.
Previously, he worked as a research scientist in the Data Science Lab at JD.com from Aug 2018 to July 2019 and a postdoc researcher in The University of Hong Kong from July 2019 to Dec 2020.
Interests
His general research interests focus on data mining and applied machine learning,
in particular, on graph mining, semi-supervised learning and part of NLP related tasks.
Generally speaking, he has spent lots of efforts in classification, clustering, link prediction and other generative tasks in graphs.
Moreover, he likes to explore some misc problems of challenge, such as reinforcement learning, crowdsourcing and NLP techniques.
Specifically, his research interests include:
- Machine learning: semi-supervised learning, self-supervised learning, weakly-supervised learning, graph-based learning;
- Data mining: graph neural networks, heterogeneous graph mining, OOD generalizability;
- Language processing: large language models (LLMs), code representation learning, prompt tuning;
- Data privacy: federated learning, data heterogeneity, model heterogeneity.
