Education background

Bachelor of Computer Science, Peking University, Beijing, China, 1999;

Ph.D. in Computer Science, University of Minnesota, USA, 2005.

Areas of Research Interests

Data Mining, Machine Learning

Research Status

My research group focuses on fundamental problems in data mining and machine learning and their applications on scientific data and urban spatial-temporal data. Recently, we addressed the problem of uncertainty qualification for deep neural networks and proposed a novel way of estimating model uncertainty by using both training and test-time augmentation. We also proposed novel indexing methods for big spatial-temporal data, based on which K-nn and reachability queries can be answered effectively to support various real-world applications, such as ride sharing and containing disease spreading.
