If you have a question about this talk, please contact Dr Sergio Bacallado.

In this talk we will survey available results and open questions on detectability of communities using polynomial-time algorithms for several variants of the stochastic block model (SBM). We will in particular consider degree-corrected SBM ’s and labelled SBM ’s and discuss how the phase transition captured by the so-called Kesten-Stigum threshold in the classical case translates in these other two scenarios.

This talk is part of the Statistics series.
