%description
Given any graph, the 'node2vec' algorithm can learn continuous feature
representations for the nodes, which can then be used for various
downstream machine learning tasks.The techniques are detailed in the paper
"node2vec: Scalable Feature Learning for Networks" by Aditya Grover, Jure
Leskovec(2016),available at <arXiv:1607.00653>.
