Abstract: Stochastic networks in general and stochastic block models in particular attracted a lot of attention in the last decade. The Popularity Adjusted Block model (PABM) is considered, which generalizes the Stochastic Block model and the Degree Corrected Block Model by allowing more flexibility for block probabilities. We argue that the main appeal of the PABM is its less rigid spectral structure which makes the PABM an attractive choice for modeling networks that appear in biological sciences.
