Web25 de jan. de 2010 · We consider a generalization of stochastic bandits where the set of arms, $\\cX$, is allowed to be a generic measurable space and the mean-payoff function is "locally Lipschitz" with respect to a dissimilarity function that is known to the decision maker. Under this condition we construct an arm selection policy, called HOO (hierarchical … WebHierarchical Optimistic Optimization (HOO) algorithm for solving the result-ing mathematical models. Machine learning methods and, in particular, bandit learning have already been used in portfolio optimization [14]. However, this is the ﬁrst time that a machine learning approach, and in particular HOO, is
