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 "average reward reinforcement learning with unknown mixing times"):
  Abstract: We derive and analyze learning algorithms for policy evaluation, apprenticeship learning, and policy gradient for average reward criteria. Existing algorithms explicitly require an upper bound on the mixing time. In contrast, we build on ideas from Markov chain theory and derive sampling algorithms that do not require such an upper bound. For these algorithms, we provide theoretical bounds on their sample-complexity and running time.

Includes members:
  Member "scalable bilinear pi learning using state and action features":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "reinforcement learning via fenchel rockafellar duality")
  Member "primal dual π learning sample complexity and sublinear run time for ergodic markov decision problems":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "voting based multi agent reinforcement learning for intelligent iot")
  Member "infinite horizon policy gradient estimation":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "multi step model agnostic meta learning convergence and improved algorithms")
