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 "the necessary and sufficient condition for generalized demixing"):
  Abstract: Demixing is the problem of identifying multiple structured signals from a superimposed observation. This work analyzes a general framework, based on convex optimization, for solving demixing problems. We present a new solution to determine whether or not a specific convex optimization problem built for generalized demixing is successful. This solution will also bring about the possibility to estimate the probability of success by the approximate kinematic formula.

Includes members:
  Member "the achievable performance of convex demixing":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "exact matrix completion based on low rank hankel structure in the fourier domain")
  Member "living on the edge phase transitions in convex programs with random data":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "on the convex geometry of blind deconvolution and matrix completion")
  Member "stable restoration and separation of approximately sparse signals":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "boosting occluded image classification via subspace decomposition based estimation of deep features")
