Web23 ian. 2024 · What is Multi-Armed Bandit? The multi-armed bandit problem is a classic problem that well demonstrates the exploration vs exploitation dilemma. Imagine you are in a casino facing multiple slot machines and each is configured with an unknown probability of how likely you can get a reward at one play.

Web1 Multi-armed bandits The model consists of some nite set of actions A(the arms of the multi-armed bandit). We denote by K = jAjthe number of actions. Each time an action is chosen, some reward r 2R is received. No information is known about the rewards the other actions would have provided. The successive rewards WebThe Multi-Armed Bandit (MAB) Problem Multi-Armed Bandit is spoof name for \Many Single-Armed Bandits" A Multi-Armed bandit problem is a 2-tuple (A;R) Ais a known set of m actions (known as \arms") Ra(r) = P[rja] is an unknown probability distribution over rewards At each step t, the AI agent (algorithm) selects an action a t 2A max and ermas location
