Mathematical Theories of Interation with Oracles
The key insight underlying this thesis is that the right kind of interaction is the key to making the intractable tractable. This work specifically investigates this insight in the context of learning
theory. While much of the learning theory literature has traditionally focused on protocols that are either non-interactive or involving unrealistically strong forms of interaction, there have
recently been several exciting advances in the design and analysis of methods for realistic interactive learning protocols.
Perhaps one of the most interesting of these is active learning. In active learning, a learning algorithm is given access to a large pool of unlabeled examples, and is allowed to sequentially request their labels so as to learn how to accurately predict the labels of new examples. This thesis contains a number of interesting advances in our understanding of the capabilities of active learning methods. Specifically, I summarize the main contributions below.
