WebWe consider the Multi-Armed Bandit (MAB) setting (e.g., Cesa-Bianchi and Lugosi, 2006), which captures many online learning problems wherein an algorithm chooses sequentially among a ﬁxed set of alternatives, traditionally called “arms”. In each round an algorithm chooses an arm and collects the corresponding reward.

Webcent work has focused on multi-armed bandits with (inﬁnitely) many arms, where one needs to assume extra structure in order to make the problem tractable. In particular, in the Lipschitz MAB problem there is an underlying similarity metric space, known to the algorithm, such that any two arms that are close in this metric space have similar ...
