Multi-View Network Embedding Via Graph Factorization Clustering and Co-Regularized Multi-View Agreement

no code implementations6 Nov 2018 Yiwei Sun, Ngot Bui, Tsung-Yu Hsieh, Vasant Honavar

Our experiments with several benchmark real-world single view networks show that GFC-based SVNE yields network embeddings that are competitive with or superior to those produced by the state-of-the-art single view network embedding methods when the embeddings are used for labeling unlabeled nodes in the networks.
