human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "a review of feature and data fusion with medical images"
  Abstract: The fusion techniques that utilize multiple feature sets to form new features that are often more robust and contain useful information for future processing are referred to as feature fusion. The term data fusion is applied to the class of techniques used for combining decisions obtained from multiple feature sets to form global decisions. Feature and data fusion interchangeably represent two important classes of techniques that have proved to be of practical importance in a wide range of medical imaging problems

Connected through hyperedge HE-1 (induced by source paper "semantic deep intermodal feature transfer transferring feature descriptors between imaging modalities"):
  with members:
    - "learning representations for automatic colorization"
    - "image to image translation with conditional adversarial networks"
    - "colorful image colorization"
    - "adam a method for stochastic optimization"
    - "very deep convolutional networks for large scale image recognition"
    - "medical image fusion a survey of the state of the art"
