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 "private text classification"):
  Abstract: Confidential text corpora exist in many forms, but do not allow arbitrary sharing. We explore how to use such private corpora using privacy preserving text analytics. We construct typical text processing applications using appropriate privacy preservation techniques (including homomorphic encryption, Rademacher operators and secure computation). We set out the preliminary materials from Rademacher operators for binary classifiers, and then construct basic text processing approaches to match those binary classifiers.

Includes members:
  Member "fast learning from distributed datasets without entity matching":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "private federated learning on vertically partitioned data via entity resolution and additively homomorphic encryption")
  Member "rademacher observations private data and boosting":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "private federated learning on vertically partitioned data via entity resolution and additively homomorphic encryption")
