Perfect Clustering for Stochastic Blockmodel Graphs via Adjacency Spectral Embedding

2 Oct 2013  ·  Vince Lyzinski, Daniel Sussman, Minh Tang, Avanti Athreya, Carey Priebe ·

Vertex clustering in a stochastic blockmodel graph has wide applicability and has been the subject of extensive research. In thispaper, we provide a short proof that the adjacency spectral embedding can be used to obtain perfect clustering for the stochastic blockmodel and the degree-corrected stochastic blockmodel. We also show an analogous result for the more general random dot product graph model.
