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 "rapid convergence of the unadjusted langevin algorithm log sobolev suffices"):
  Abstract: We prove a convergence guarantee on the unadjusted Langevin algorithm for sampling assuming only that the target distribution $e^{-f}$ satisfies a log-Sobolev inequality and the Hessian of $f$ is bounded. In particular, $f$ is not required to be convex or have higher derivatives bounded.

    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "learning halfspaces with massart noise under structured distributions")
