Bubeck bandits
WebJun 16, 2013 · We study the problem of exploration in stochastic Multi-Armed Bandits. Even in the simplest setting of identifying the best arm, there remains a logarithmic multiplicative gap between the known lower and upper bounds for the number of arm pulls required for the task. ... Gabillon, V., Ghavamzadeh, M., Lazaric, A., and Bubeck, S. Multi-bandit ... Webnear-optimal algorithms for the adversarial multi-armed bandit problem. We summarize our main results: 1. We show that regularization via the Tsallis entropy leads to the state-of-the-art adversarial MAB algorithm, matching the minimax regret rate of Audibert and Bubeck (2009) with a tighter con-stant. Interestingly, our algorithm fully ...

WebS´ebastien Bubeck∗Nicolo Cesa-Bianchi†Ga´bor Lugosi‡ September 11, 2012 Abstract The stochastic multi-armed bandit problem is well understood when the reward distributions are sub-Gaussian. In this paper we examine the bandit problem under the weaker assumption that the distributions have moments of order 1 + ε, for some ε∈ (0,1]. WebJul 11, 2016 · Kernel-based methods for bandit convex optimization. Sébastien Bubeck, Ronen Eldan, Yin Tat Lee. We consider the adversarial convex bandit problem and we build the first \mathrm {poly} (T) -time algorithm with \mathrm {poly} (n) \sqrt {T} -regret for this problem. To do so we introduce three new ideas in the derivative-free optimization ...

WebA well-studied class of bandit problems with side information are “contextual bandits” Langford and Zhang (2008); Agarwal et al. (2014). Our framework bears a superficial similarity to contextual bandit problems since the extra observations on non-intervened variables might be viewed as context for selecting an intervention. corsair psu serial number checkWebStochastic Multi-Armed Bandits with Heavy Tailed Rewards We consider a stochastic multi-armed bandit problem defined as a tuple (A;fr ag) where Ais a set of Kactions, and r a2[0;1] is a mean reward for action a.
