Statistics Colloquium

Abstract:
Model-based clustering of dynamic networks has emerged as an essential research topic in statistical network analysis. We present a principled statistical clustering of dynamic networks through the temporal exponential-family random graph models with a hidden Markov structure. The temporal exponential-family random graph models allow us to detect groups based on interesting features of the dynamic networks and the hidden Markov structure is used to infer the time-evolving block structure of dynamic networks. The power of our proposed method is demonstrated in real-world applications.
