Spectral Clustering on Spherical Coordinates Under the Degree-Corrected Stochastic Blockmodel
Spectral Clustering on Spherical Coordinates Under the Degree-Corrected Stochastic Blockmodel
Spectral clustering is a popular method for community detection in network graphs: starting from a matrix representation of the graph, the nodes are clustered on a low dimensional projection obtained from a truncated spectral decomposition of the matrix. Estimating correctly the number of communities and the dimension of the reduced …
