Abstract: The dissertation examines the role of concentration inequalities in efforts to improve performance bounds of supervised learning algorithms. The motivation to obtain tight generalization error and excess risk bounds in statistical learning theory comes from the belief that a deep understanding of a learning process might lead us to new useful ideas and more accurate algorithms. First part of the work studies concentration inequalities for one particular setting of dependent random variables: when they are sampled without replacement from the given finite population. We provide two novel Bernstein-style concentration inequalities for suprema of empirical processes and sampling without replacement. While these new inequalities may potentially have broad applications, we exemplify their significance in the second part of the work by studying the transductive setting of statistical learning theory. For which we provide an excess risk bound based on the localized complexity of the hypothesis class which holds under very mild assumptions. Finally, the third part of the work studies the PAC-Bayesian analysis, which is a general tool for data-dependent analysis in machine learning. We derive a new PAC-Bayes-Empirical-Bernstein inequality which is a powerful Bernstein-style concentration inequality depending only on empirical quantities. We show that in a number of interesting situations our new PAC-Bayes-Empirical-Bernstein bound can be significantly tighter than the state-of-the-art results.
