Research Interests: My general research interests are in machine learning, reasoning under uncertainty, databases and artificial intelligence. Other topics of interest to me include: data integration, database query optimization and approximate query processing, entity resolution, information extraction, utility elicitation, planning under uncertainty, contraint-based reasoning, abstraction and problem reformulation. The theme of my research is building and using statistical models of structured, semi-structured and unstructured data to do useful things.

Postdoctoral Researchers

Jay Pujara, Ph.D. Degree 2015, University of Maryland
jpujara AT ucsc.edu
E2, Room 485
http://cs.umd.edu/~jay/

Research Interests: I develop scalable machine learning techniques for statistical relational learning. This requires confronting challenges such as millions of dependencies between predictions, noisy evidence, and budgeted feature acquisition. Example applications include knowledge base construction, collective entity resolution, hierarchical topic modeling, active semi-supervised learning and cascade classifiers for hierarchical labels.
