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 "sparsity aware learning and compressed sensing an overview"):
  Abstract: This paper is based on a chapter of a new book on Machine Learning, by the first and third author, which is currently under preparation. We provide an overview of the major theoretical advances as well as the main trends in algorithmic developments in the area of sparsity-aware learning and compressed sensing. Both batch processing and online processing techniques are considered. A case study in the context of time-frequency analysis of signals is also presented. Our intent is to update this review from time to time, since this is a very hot research area with a momentum and speed that is sometimes difficult to follow up.
