Title:      New Algorithms for Contextual Bandits

Abstract: This talk will focus on the contextual bandit problem, which
essentially captures many situations from medical testing to computational
advertising.  In this setting, a learner only discovers about the actions
it takes, creating a need for balancing exploiting good strategies and
exploring new ones.  I will discuss some recent results on the contextual
bandit problem, including the first high-probability optimal algorithm, a
reduction from bandits to cost-sensitive learning, as well as an
interesting generalization of the bandit setting.  These advances point to
the possibility of launching better and more effective algorithms in
practice.
