info

I am a project scientist with the Machine Learning Department at Carnegie Mellon University, where I'm working with Carlos Guestrin on probabilistic inference for large-scale problems.

My current research focus is on using kernel methods to reveal properties and relations in data. These methods include tests for strength of dependence, for example in measuring how strongly two bodies of text in different languages are related; testing for similarities in two datasets, which can be used in attribute matching for databases (that is, automatically finding which fields of two databases correspond); and testing for conditional dependence, which is useful in detecting redundant variables that carry no additional predictive information, given the variables already observed.
