- I am a machine learning engineer at Databricks.
- My research interests include 1). information retrieval, recommender system, ecommerce personalization 2). NLP applications: question answering, semantic parsing, 3) data driven machine learning and transfer learning.
- I got my Master of Mathematics (Computer Science) degree (Thesis-based) at the University of Waterloo. I was fortunated to be supervised by Jimmy Lin at the Data System group and work with him for two years.
- I got my B.S. degree in computer science and technology at Zhejiang University. I also worked as a research assistant with Professor Lu Wei in the winter of 2017 (actually there is no winter in Singapore).
