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 "plume polyhedral learning using mixture of experts"):
  Abstract: In this paper, we propose a novel mixture of expert architecture for learning polyhedral classifiers. We learn the parameters of the classifierusing an expectation maximization algorithm. Wederive the generalization bounds of the proposedapproach. Through an extensive simulation study, we show that the proposed method performs comparably to other state-of-the-art approaches.

Includes members:
  Member "a vector contraction inequality for rademacher complexities":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "learning state abstractions for transfer in continuous control")
  Member "geometric decision tree":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "on the robustness of decision tree learning under label noise")
