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 "information theoretic privacy for distributed average consensus bounded integral inputs"):
  Abstract: We propose an asynchronous distributed average consensus algorithm that guarantees information-theoretic privacy of honest agents' inputs against colluding passive adversarial agents, as long as the set of colluding passive adversarial agents is not a vertex cut in the underlying communication network. This implies that a network with $(t+1)$-connectivity guarantees information-theoretic privacy of honest agents' inputs against any $t$ colluding agents. The proposed protocol is formed by composing a distributed privacy mechanism we provide with any (non-private) distributed average consensus algorithm. The agent' inputs are bounded integers, where the bounds are apriori known to all the agents.

Includes members:
  Member "differentially private distributed optimization":
    also connected through other hyperedges:

  Member "differentially private iterative synchronous consensus":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "privacy preserving distributed machine learning via local randomization and admm perturbation")
