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: "pac bayes with backprop"
  Abstract: We explore a method to train probabilistic neural networks by minimizing risk upper bounds, specifically, PAC-Bayes bounds. Thus randomization is not just part of a proof strategy, but part of the learning algorithm itself. We derive two training objectives, one from a previously known PAC-Bayes bound, and a second one from a novel PAC-Bayes bound. We evaluate both training objectives on various data sets and demonstrate the tightness of the risk upper bounds achieved by our method. Our training objectives have sound theoretical justification, and lead to self-bounding learning where all the available data may be used to learn a predictor and certify its risk, with no need to follow a data-splitting protocol.
