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 "learning first order definable concepts over structures of small degree"):
  Abstract: We consider a declarative framework for machine learning where concepts and hypotheses are defined by formulas of a logic over some background structure. We show that within this framework, concepts defined by first-order formulas over a background structure of at most polylogarithmic degree can be learned in polylogarithmic time in the "probably approximately correct" learning sense.

Includes members:
  Member "machine learning with guarantees using descriptive complexity and smt solvers":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "learning definable hypotheses on trees")
  Member "abstract learning frameworks for synthesis":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "decidable synthesis of programs with uninterpreted functions")
  Member "learning and verifying quantified boolean queries by example":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "example driven query intent discovery abductive reasoning using semantic similarity")
  Member "first order query evaluation on structures of bounded degree":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "first order interpretations of bounded expansion classes")
