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 "a characterization of the dirichlet distribution with application to learning bayesian networks"):
  Abstract: We provide a new characterization of the Dirichlet distribution. This characterization implies that under assumptions made by several previous authors for learning belief networks, a Dirichlet prior on the parameters is inevitable.

Includes members:
  Member "learning bayesian networks the combination of knowledge and statistical data":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "a tutorial on learning with bayesian networks")
  Member "learning gaussian networks":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "causal discovery with reinforcement learning")
  Member "theory refinement on bayesian networks":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "a tutorial on learning with bayesian networks")
  Member "learning bayesian networks a unification for discrete and gaussian domains":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "scaling up hybrid probabilistic inference with logical and arithmetic constraints via message passing")
  Member "operations for learning with graphical models":
    also connected through other hyperedges:
      - Hyperedge HE-5 (induced by source paper "state space abstractions for probabilistic inference a systematic review")
