Abstract: In this paper, we study the stochastic block model (SBM) with growing number of clusters and bounded degree. Specifically, for SBM Gsn(n,an,bn) with diverging sn blocks and fixed a and b(a>b>0), we prove that if (a−b)2Keywords: Community detection; Random graph; Networks; Stochastic block model (search for similar items in EconPapers)
