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: "fourier rnns for sequence analysis and prediction"
  Abstract: Fourier methods have a long and proven track record in as an excellent tool in data processing. We propose to integrate Fourier methods into complex recurrent neural network architectures and show accuracy improvements on analysis and prediction tasks as well as computational load reductions. We predict synthetic data drawn from the synthetic-Lorenz equations as well as real world human motion prediction. We demonstrate the setup's analysis capabilities on the task of music recognition.

Connected through hyperedge HE-1 (induced by source paper "fast fourier forecasting resource utilisation in distributed systems"):
  with members:
    - "online collection and forecasting of resource utilization in large scale distributed systems"
    - "complex gated recurrent neural networks"
    - "learning phrase representations using rnn encoder decoder for statistical machine translation"
    - "fast training of convolutional networks through ffts"
