WebMulti-armed bandits model is composed of an M arms machine. Each arm can get rewards when drawing the arm, and the arm pulling distribution is unknown. The arm is drawn and gets a reward at each time step. Choosing which of these arms to draw and maximize the sum of the rewards is the target.

Webin the Constrained Multi-Armed Bandit (CMAB) literature, including bandits with knapsacks, bandits with fairness constraints, etc. Details about these problems and how they fit into our framework are provided in Section 1.1. Specifically, we consider an agent’s online decision problem faced with a fixed finite set ofNarms
Webresults such as tight (log T) distribution-dependent and (p T) distribution-independent upper and lower bounds on the regret in Trounds [19,2,1]. An important extension to the classical MAB problem is combinatorial multi-armed bandit (CMAB). In CMAB, the player selects not just one arm in each round, but a subset of arms or a combinatorial raww foundationWeb1 oct. 2010 · Abstract In the stochastic multi-armed bandit problem we consider a modification of the UCB algorithm of Auer et al. [4]. For this modified algorithm we give an improved bound on the regret with respect to the optimal reward. While for the original UCB algorithm the regret in K-armed bandits after T trials is bounded by const · … raw whale meatWebStochastic Multi-Armed Bandits with Unrestricted delay distributions observed reward of a sub-optimal arm, which makes the learning task substantially more challenging. 1.1Our contributions We consider both the reward-independent and reward-dependent versions of stochastic MAB with delays.

Dynamic Pricing as A Multi-Armed Bandit Dynamic pricing can be formulated as a special multi-armed bandit (MAB) problem, and the connection was explored as early as 1974 by Rothschild in [1].
