TM is a recent machine learning approach to pattern recognition that employs a team of non-contextual bandit algorithms, in the form of Tsetlin automata [27], to learn patterns expressed in propositional logic. earn interest on crypto reddit WebContextual multi-armed bandit has shown to be an effective tool in recommender systems. In this paper, we study a novel problem of multi-facet bandits involving a group of bandits, each characterizing the users' needs from one unique aspect. In each round, for the given user, we need to select one arm from each bandit, such that the combination ...
