Efficient Learning Algorithms with Limited Information
De, Anindya
ProQuest LLC, Ph.D. Dissertation, University of California, Berkeley
The thesis explores efficient learning algorithms in settings which are more restrictive than the PAC model of learning (Valiant) in one of the following two senses: (i) The learning algorithm has a very weak access to the unknown function, as in, it does not get labeled samples for the unknown function (ii) The error guarantee required from the hypothesis is more stringent than the PAC model. Ever since its introduction, the PAC model of learning is considered as the standard model of learning. However, there are many situations encountered in practice in which the PAC model does not adequately model the learning problem in hand. To meet this limitation, several other models have been introduced for e.g. the "agnostic learning" model, the "restricted focus of attention" model, the "positive examples only" model amongst others. The last two models are the ones which are most relevant to the work in this thesis. Beyond the motivation of modeling learning problems, another reason to consider these alternate models is because of the rich interplay between the questions arising here and other areas like computational complexity theory and social choice theory. Further, the study of these models lead to interesting questions in discrete Fourier analysis and probability theory. In fact, the connections forged between these learning questions and Fourier analysis and probability theory are key to the results in this thesis. (Abstract shortened by UMI.).
