2010. Nonparametric Bandits with Covariates

With Assaf Zeevi

In COLT (A. T. Kalai and M. Mohri, eds.). Omnipress, 54-66.

*covariate*. The goal is to maximize cumulative expected reward. We derive general lower bounds on the performance of any admissible policy, and develop an algorithm whose performance achieves the order of said lower bound up to logarithmic terms. This is done by decomposing the global problem into suitably ``localized'' bandit problems. Proofs blend ideas from nonparametric statistics and traditional methods used in the bandit literature.
