I am a research scientist at Google. Before Google, I worked in the deep learning group, Microsoft Research and Baidu Silicon Valley AI Lab. I am interested in machine learning and their applications to speech, translation and natural language understanding. I received my PhD from Princeton University. (Advisor: David M. Blei) If you are a Ph.D. student interested in a research internship working with me at Google, please send me an email with your resume and research interests at chongw@[companyname].com.

Some Awards:

• Google PhD fellow and Siebel Scholar
• Paper awards or honorable mentions at NIPS, AISTATS, KDD

Research Highlights:

• Research on a generic loss function for sequence modeling through segmentations. (1) Sequence Modeling via Segmentations; (2) Towards Neural Phrase-based Machine Translation (code); (3) Subgoal Discovery for HRL.
• Research on lookahead convolution architecture enabled the deployment of an end-to-end speech recognition system to benefit hundreds of millions of users (http://maps.baidu.com) by significantly reducing the latency. See a torch implementation.
• Research on collaborative topic modeling is used by New York Times for their recommendation engine.
