Asymptotic analysis of the stochastic block model for modular networks and its algorithmic applications

14 Sep 2011Aurelien DecelleFlorent KrzakalaCristopher MooreLenka Zdeborová

In this paper we extend our previous work on the stochastic block model, a commonly used generative model for social and biological networks, and the problem of inferring functional groups or communities from the topology of the network. We use the cavity method of statistical physics to obtain an asymptotically exact analysis of the phase diagram... (read more)
