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 "info clustering an efficient algorithm by network information flow"):
  Abstract: Motivated by the fact that entities in a social network or biological system often interact by exchanging information, we propose an efficient info-clustering algorithm that can group entities into communities using a parametric max-flow algorithm. This is a meaningful special case of the info-clustering paradigm where the dependency structure is graphical and can be learned readily from data.

Includes members:
  Member "info clustering a mathematical theory for data clustering":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "secret key agreement for hypergraphical sources with limited total discussion")
  Member "minimax rates of entropy estimation on large alphabets via best polynomial approximation":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "to split or not to split the impact of disparate treatment in classification")
