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 "looking to listen at the cocktail party a speaker independent audio visual model for speech separation"):
  Abstract: A trained, machine learning model that utilizes both the visual and auditory signals of an input video to separate the speech of different speakers in the video.

Includes members:
  Member "the conversation deep audio visual speech enhancement":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "audio visual speech enhancement using conditional variational auto encoder")
  Member "learning to separate object sounds by watching unlabeled video":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "the state of service robots current bottlenecks in object perception and manipulation")
  Member "the fifth chime speech separation and recognition challenge dataset task and baselines":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "on loss functions for supervised monaural time domain speech enhancement")
  Member "the sound of pixels":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "the state of service robots current bottlenecks in object perception and manipulation")
  Member "audio visual scene analysis with self supervised multisensory features":
    also connected through other hyperedges:
      - Hyperedge HE-5 (induced by source paper "multi modal self supervision from generalized data transformations")
  Member "improved speech reconstruction from silent video":
    also connected through other hyperedges:
      - Hyperedge HE-6 (induced by source paper "mobivsr a visual speech recognition solution for mobile devices")
  Member "supervised speech separation based on deep learning an overview":
    also connected through other hyperedges:
      - Hyperedge HE-7 (induced by source paper "temporal spatial neural filter direction informed end to end multi channel target speech separation")
  Member "visual speech enhancement":
    also connected through other hyperedges:
      - Hyperedge HE-8 (induced by source paper "audio visual speech enhancement using conditional variational auto encoder")
