WebMotivated by these issues, we propose a novel local linear graphon estimator that uses covariates to account for node heterogeneity, and enables improved graphon estimation. We consider the setting where a single undirected network without self-loops is observed along with continuous covariates at each node. WebIn this study, we propose the multi-view feature interpretable change point detection method (MICPD), which is based on a vector autoregressive (VAR) model to encode high-dimensional network data into a low-dimensional representation, and locate change points by tracking the evolution of multiple targets and their interactions across the whole ...

A Graphon-based Framework for Modeling Large Networks

WebNonparametric methods for undirected networks have focused on estimation of the graphon model. While the graphon model accounts for nodal heterogeneity, it does not account for network heterogeneity, a feature speci c to applications where multiple networks are observed. To address this setting of multiple networks, we propose a multi-graphon … WebDynamic network models and graphon estimation.
