WebFeb 20, 2012 · [Submitted on 20 Feb 2012] The best of both worlds: stochastic and adversarial bandits Sebastien Bubeck, Aleksandrs Slivkins We present a new bandit algorithm, SAO (Stochastic and Adversarial Optimal), whose regret is, essentially, optimal both for adversarial rewards and for stochastic rewards. 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]. hdfc business loan dsa https://segatex-lda.com

Both the m-best arms identi cation and the multi-bandit best arm identi cation have numerous poten-tial applications. We refer the interested reader to the previously cited papers for several examples. 2. Problem setup We adopt the terminology of multi-armed bandits. WebStochastic 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. For each round t, the agent chooses an action a tbased on its exploration strategy and, then, get a stochastic reward: R t;a:= r a+ t ...
