Ofer Meshi's Home Page
I am a Research Assistant Professor at the Toyota Technological Institute at Chicago , a philanthropically endowed academic computer science institute located on the University of Chicago campus.
I obtained my Ph.D. and M.Sc. in Computer Science from the Hebrew University of Jerusalem, where I worked with Amir Globerson and Nir Friedman . My B.Sc. in Computer Science is from Tel Aviv University.
My research is in Machine learning and optimization. In particular, I am interested in finding efficient algorithms for: structured output prediction, probabilistic graphical models, model selection, statistical relational models and other related problems.
