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 "nearly optimal risk bounds for kernel k means"):
  Abstract: In this paper, we study the statistical properties of the kernel $k$-means and obtain a nearly optimal excess risk bound, substantially improving the state-of-art bounds in the existing clustering risk analyses. We further analyze the statistical effect of computational approximations of the Nystr\"{o}m kernel $k$-means, and demonstrate that it achieves the same statistical accuracy as the exact kernel $k$-means considering only $\sqrt{nk}$ Nystr\"{o}m landmark points. To the best of our knowledge, such sharp excess risk bounds for kernel (or approximate kernel) $k$-means have never been seen before.

  Member "scalable kernel k means clustering with nystrom approximation relative error bounds":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "diversity sampling is an implicit regularization for kernel methods")
  Member "on the equivalence between quadrature rules and random features":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "large scale kernel methods and applications to lifelong robot learning")
  Member "learning manifolds with k means and k flats":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "estimating a manifold from a tangent bundle learner")
