Research Interests

I am interested in problems appearing in the analysis of classic models of statistics and statistical learning. This includes the mathematics behind the sample complexity analysis for different learning algorithms in classiffcation and regression, general dependence on noise and adaptivity as well as combinatorics of VC classes, PAC learning, and the sample compression. I am also interested in theoretical guarantees for the learning in a presence of unlabeled data (semi-supervised and transductive learning) under minimal restrictions on the model.
