Web26 nov. 2024 · A common strategy is called the Upper-Confidence-Bound Action selection, in short, UCB. If you are an optimist, you will like this one! It’s strategy is : Optimism in the face of uncertainty. This method selects the action according to its potential, captured in the Upper-Confidence interval. Web24 iul. 2024 · Abstract: In this paper, we analyze the regret bound of Multi-armed Bandit (MAB) algorithms under the setting where the payoffs of an arbitrary-size cluster of arms are observable in each round. Compared to the well-studied bandit or full feedback setting, where the payoffs of the selected arm or all the arms are observable, the clustered …
Web9 mai 2024 · This paper studies a new variant of the stochastic multi-armed bandits problem where auxiliary information about the arm rewards is available in the form of control variates.
