Network Cross-Validation for Determining the Number of Communities in Network Data
Network Cross-Validation for Determining the Number of Communities in Network Data
The stochastic block model (SBM) and its variants have been a popular tool for analyzing large network data with community structures. In this article, we develop an efficient network cross-validation (NCV) approach to determine the number of communities, as well as to choose between the regular stochastic block model and …
