TITLE: “Change point estimation in dynamic stochastic block model”
ABSTRACT: We shall consider a dynamic stochastic block model with single change point. An easily implementable algorithm based on maximum pseudo-likelihood method and spectral clustering will be proposed for estimating the change point. We shall also estimate the edge-probability matrices and community structures before and after the change point. The convergence rate and asymptotic distribution for these estimators will be discussed and compared with other existing works in the literature. This is joint work with Moulinath Banerjee and George Michailidis.
