%description
Network sparsification with a variety of novel and known network
sparsification techniques. All network sparsification techniques reduce
the number of edges, not the number of nodes. Network sparsification is
sometimes referred to as network dimensionality reduction. This package is
based on the work of Spielman, D., Srivastava, N. (2009)<arXiv:0803.0929>.
