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 vector contraction inequality for rademacher complexities"):
  Abstract: The contraction inequality for Rademacher averages is extended to Lipschitz functions with vector-valued domains, and it is also shown that in the bounding expression the Rademacher variables can be replaced by arbitrary iid symmetric and sub-gaussian variables. Example applications are given for multi-category learning, K-means clustering and learning-to-learn.

Includes members:
  Member "generalization error bounds for learning to rank does the length of document lists matter":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "an alternative cross entropy loss for learning to rank")
  Member "multi class svms from tighter data dependent generalization bounds to novel algorithms":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "learning vector valued functions with local rademacher complexity")
  Member "convex learning of multiple tasks and their structure":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "weakly supervised open set domain adaptation by dual domain collaboration")
  Member "regularization techniques for learning with matrices":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "distributed learning with sublinear communication")
  Member "a model of inductive bias learning":
