Abstract

We study the framework of online learning, when individual examples are corrupted by random noise, and both examples and noise type can be cho- sen adversarially. Previous work has shown that without knowledge of the noise distribution, it is possible to learn using a random, potentially un- bounded number of independent noisy copies of each example. Moreover, it is generally impossible to learn with just one noisy copy per example. In this paper, we explore the consequences of being given some side informa- tion on the noise distribution. We consider several settings, and show how one can learn linear and kernel-based predictors using just one or two noisy views of each example, depending on the side information provided.
