human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "robustly leveraging prior knowledge in text classification"):
  Abstract: Prior knowledge has been shown very useful to address many natural language processing tasks. Many approaches have been proposed to formalise a variety of knowledge, however, whether the proposed approach is robust or sensitive to the knowledge supplied to the model has rarely been discussed. In this paper, we propose three regularization terms on top of generalized expectation criteria, and conduct extensive experiments to justify the robustness of the proposed methods. Experimental results demonstrate that our proposed methods obtain remarkable improvements and are much more robust than baselines.

Includes members:
  Member "learning from sparse data by exploiting monotonicity constraints":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "learning credible models")
  Member "cross task knowledge constrained self training":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "learning how to self learn enhancing self training using neural reinforcement learning")
