Uncertainty quantification for mixed membership in multilayer networks with degree heterogeneity using Gaussian variational inference
Fangzheng Xie, Hsin-Hsiung Huang
Analyzing multilayer networks is central to understanding complex relational measurements collected across multiple conditions or over time. A pivotal task in this setting is to qu…

SANVI: A Fast Spectral-Assisted Network Variational Inference Method with an Extended Surrogate Likelihood Function
Dingbo Wu, Fangzheng Xie
Bayesian inference has been broadly applied to statistical network analysis, but suffers from the expensive computational costs due to the nature of Markov chain Monte Carlo sampli…

Statistical inference of random graphs with a surrogate likelihood function
Dingbo Wu, Fangzheng Xie
Spectral estimators have been broadly applied to statistical network analysis, but they do not incorporate the likelihood information of the network sampling model. This paper prop…
