I am now working in Alibaba Group @Beijing Wangjing.

I obtained my Ph.D from Department of Computer Science at UC Berkeley, where I worked with Professor John Canny.

Prior to Berkeley, I studied Computer Science at Tsinghua University

Research Interest

Machine learning algorithm and system (deep or not), Data Visualization

I am interested in building toolkits for modern data scientists who will usually work on prototyping new models or running experiments on large scale dataset. Our methodology includes but not limit to using hardware accelerations like GPU, providing implementation framework for machine learning algorithms, building visual interface for real-time control and monitoring.
I am also interested in interpreting deep learning algorthims (Either their behavior or training process).

Check out our BIDMach project and X-DeepLearning project.
