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: "within brain classification for brain tumor segmentation"
  Abstract: Purpose#R##N#In this paper, we investigate a framework for interactive brain tumor segmentation which, at its core, treats the problem of interactive brain tumor segmentation as a machine learning problem.

Connected through hyperedge HE-1 (induced by source paper "deep learning trends for focal brain pathology segmentation in mri"):
  with members:
    - "brain tumor segmentation with deep neural networks"
    - "deep convolutional neural networks for computer aided detection cnn architectures dataset characteristics and transfer learning"
    - "hemis hetero modal image segmentation"
    - "the importance of skip connections in biomedical image segmentation"
    - "u net convolutional networks for biomedical image segmentation"
    - "parallel multi dimensional lstm with application to fast biomedical volumetric image segmentation"
    - "deep residual learning for image recognition"
    - "deep convolutional networks for pancreas segmentation in ct imaging"
