Tutorial on NLP-Inspired Network Embedding

This tutorial covers a few papers in the field of network embedding. Network embedding is a collective term for techniques for mapping graph nodes to vectors of real numbers in a multidimensional space. To be useful, a good embedding should preserve the structure of the graph. The vectors can then be used as input to various network and graph analysis tasks, such as link prediction. The papers discussed develop methods for the online learning of such embeddings, and include DeepWalk, LINE, node2vec, struc2vec and megapath2vec. These new methods and developments in online learning of network embeddings have major applications for the analysis of graphs and networks, including online social networks.
