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 "true online emphatic td lambda quick reference and implementation guide"):
  Abstract: This document is a guide to the implementation of true online emphatic TD($\lambda$), a model-free temporal-difference algorithm for learning to make long-term predictions which combines the emphasis idea (Sutton, Mahmood & White 2015) and the true-online idea (van Seijen & Sutton 2014). The setting used here includes linear function approximation, the possibility of off-policy training, and all the generality of general value functions, as well as the emphasis algorithm's notion of "interest".

Includes members:
  Member "an emphatic approach to the problem of off policy temporal difference learning":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "discor corrective feedback in reinforcement learning via distribution correction")
  Member "on convergence of emphatic temporal difference learning":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "provably convergent two timescale off policy actor critic with function approximation")
  Member "multi timescale nexting in a reinforcement learning robot":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "improving performance in reinforcement learning by breaking generalization in neural networks")
