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.
