Top K Ranking for Multi-Armed Bandit with Noisy Evaluations.

We consider a multi-armed bandit setting where, at the beginning of each round, the learner receives noisy independent, and possibly biased, evaluations of the true reward of each arm and it selects K ... arms with the objective of accumulating as much reward as possible over T rounds. ... Multi-feedback bandit learning with probabilistic contexts. ...
