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 "defining the problem of observation learning"):
  Abstract: This article defines and formulates the problem of observation learning in robotic systems.

Includes members:
  Member "third person imitation learning":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "hierarchically decoupled imitation for morphological transfer")
  Member "unsupervised state representation learning with robotic priors a robustness benchmark":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "unsupervised visuomotor control through distributional planning networks")
  Member "end to end learning for self driving cars":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "deep reinforcement learning for autonomous driving a survey")
  Member "generative adversarial imitation learning":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "deep reinforcement learning for autonomous driving a survey")
  Member "facenet a unified embedding for face recognition and clustering":
    also connected through other hyperedges:
      - Hyperedge HE-5 (induced by source paper "discrimination aware network pruning for deep model compression")
