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 paper on oculus rift a virtual reality headset"
  Abstract: Oculus rift: Virtual reality (VR) is a burgeoning field that has the inherent potential of manipulating peoples mind with a superlative 3D experience. Oculus rift is one such application that assists in achieving the same. With the fleeting enhancements in VR it now seems very feasible to provide the user with experiences that were earlier thought to be merely a dream or a nightmare.

Connected through hyperedge HE-1 (induced by source paper "telexistence and teleoperation for walking humanoid robots"):
  with members:
    - "a control architecture with online predictive planning for position and torque controlled walking of humanoid robots"
    - "a benchmarking of dcm based architectures for position and velocity controlled walking of humanoid robots"
    - "a whole body software abstraction layer for control design of free floating mechanical systems"

Connected through hyperedge HE-2 (induced by source paper "ternary weight networks"):
  with members:
    - "squeezenet alexnet level accuracy with 50x fewer parameters and 0 5mb model size"
    - "binarized neural networks"
    - "binarized neural networks training deep neural networks with weights and activations constrained to 1 or 1"
    - "ssd single shot multibox detector"
    - "xnor net imagenet classification using binary convolutional neural networks"
    - "convolutional networks for fast energy efficient neuromorphic computing"
    - "binaryconnect training deep neural networks with binary weights during propagations"
    - "deep compression compressing deep neural networks with pruning trained quantization and huffman coding"
