human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "thresholding bandit with optimal aggregate regret"):
  Abstract: We consider the thresholding bandit problem, whose goal is to find arms of mean rewards above a given threshold $\theta$, with a fixed budget of $T$ trials. We introduce LSA, a new, simple and anytime algorithm that aims to minimize the aggregate regret (or the expected number of mis-classified arms). We prove that our algorithm is instance-wise asymptotically optimal. We also provide comprehensive empirical results to demonstrate the algorithm's superior performance over existing algorithms under a variety of different scenarios.

Includes members:
  Member "towards instance optimal bounds for best arm identification":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "collaborative learning with limited interaction tight bounds for distributed exploration in multi armed bandits")
  Member "statistical decision making for optimal budget allocation in crowd labeling":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "estimating error and bias in offline evaluation results")
