Statistical algorithms using multisets and statistical inference of heterogeneous networks
… heterogeneous version of the mixed membership stochastic blockmodel. We also apply a variational algorithm for posterior inference. We demonstrate the advantage of the proposed method, in modeling overlapping communities and multiple memberships, through simulation studies and applications to …

Statistical analysis of networks with community structure and bootstrap methods for big data
… community detection literature. We propose a blockmodel for heterogeneous networks with community structure, and introduce a heterogeneous spectral clustering algorithm for community detection in heterogeneous networks. Theoretical properties of the clustering algorithm under the proposed …

Statistical inference for complex networks
… datasets. Heterogeneous mixed-membership stochastic blockmodel (MMSB) is powerful for modeling overlapping communities and multiple community memberships, but many methods in the literature lack a theoretical guarantee. In the second project, we study the theoretical properties of the …

Modeling and projection of respondent driven network samples
… the Exponential Random Graph Model (ERGM) and a Stochastic Block Model (SBM) to an empirical study of the Facebook friendship network of 1034 participants. Then, given our goal of identifying techniques that will produce a representative sample, we decided to compare two version of AC-RDSs, in …
