Spectral and matrix factorization methods for consistent community detection in multi-layer networks

24 Apr 2017Subhadeep PaulYuguo Chen

We consider the problem of estimating a consensus community structure by combining information from multiple layers of a multi-layer network using methods based on the spectral clustering or a low-rank matrix factorization. As a general theme, these "intermediate fusion" methods involve obtaining a low column rank matrix by optimizing an objective function and then using the columns of the matrix for clustering...
