Glen Coppersmith

Senior Research Scientist; Assistant Research Scientist, Electrical and Computer Engineering. Streaming algorithms, graph based methods.

I am an assistant research professor of computer science and a research scientist at the Human Language Technology Center of Excellence (HLTCOE). I am also affiliated with the Machine Learning Group, the Center for Language and Speech Processing, and the Center for Population Health Information Technology. I have a range of research interests in machine learning, natural language processing, speech, intelligent user interfaces and health informatics. I use a variety of methods, including bayesian models, topic models, online learning, transfer learning, semi-supervised learning, and structured prediction.
