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 "lectures on randomized numerical linear algebra"):
  Abstract: This chapter is based on lectures on Randomized Numerical Linear Algebra from the 2016 Park City Mathematics Institute summer school on The Mathematics of Data.

Includes members:
  Member "structural convergence results for low rank approximations from block krylov spaces":
    also connected through other hyperedges:
      (none)
  Member "structural convergence results for approximation of dominant subspaces from block krylov spaces":
    also connected through other hyperedges:
      (none)
  Member "randomized block krylov methods for stronger and faster approximate singular value decomposition":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "homogeneous network embedding for massive graphs via reweighted personalized pagerank")
  Member "improved analyses of the randomized power method and block lanczos method":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "break the ceiling stronger multi scale deep graph convolutional networks")
  Member "near optimal column based matrix reconstruction":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "good feature matching towards accurate robust vo vslam with low latency")
  Member "randomized algorithms for matrices and data":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "solving tall dense linear programs in nearly linear time")
