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 "dppy sampling dpps with python"):
  Abstract: Determinantal point processes (DPPs) are specific probability distributions over clouds of points that are used as models and computational tools across physics, probability, statistics, and more recently machine learning. Sampling from DPPs is a challenge and therefore we present DPPy, a Python toolbox that gathers known exact and approximate sampling algorithms for both finite and continuous DPPs. The project is hosted on GitHub and equipped with an extensive documentation.

Includes members:
  Member "learning nonsymmetric determinantal point processes":
    also connected through other hyperedges:
      (none)
  Member "exact sampling of determinantal point processes with sublinear time preprocessing":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "improved guarantees and a multiple descent curve for the column subset selection problem and the nystr om method")
  Member "monte carlo markov chain algorithms for sampling strongly rayleigh distributions and determinantal point processes":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "improved guarantees and a multiple descent curve for the column subset selection problem and the nystr om method")
  Member "batched gaussian process bandit optimization via determinantal point processes":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "regret bounds for batched bandits")
