About me

I am a Senior Applied Scientist from Amazon Search. I obtained my Ph.D. degree from the Department of Computer Science and Engineering, Hong Kong University of Science and Technology (HKUST). My supervisor is Prof. Qiang Yang. Before joining HKUST, I obtained the B.Eng degree from School of Data and Computer Science, Sun Yat-sen University (SYSU). [Github][Google Scholar]

Research internship positions in Amazon Search (Base: Bay area) are available. Feel free to send your CV to me if you are interested.

Research interests

My current research is Low-Resource Natural Language Processing (LR-NLP), including cross-lingual/multilingual, cross-domain, and multi-task scenarios, etc. Revolving around this goal, I mainly study the following topics:

  • Machine Learning: transfer Learning, meta-learning, semi/weakly-supervised learning, multi-task learning, graph embedding.
  • Natural Language Processing: knowledge graph, information extraction, question answering, sentiment analysis.

Recently interesting topics: multilingual product knowledge graph, time-series graph mining, xmc: extreme multi-label classification, weakly-suprvised learning for NLP.
