Hierarchical Clustering of Networks via Hierarchical Distance Matrices
Li Chen, Nathaniel Josephs, Eric D. Kolaczyk +1
Clustering populations of networks while recovering their latent hierarchical organization is a fundamental yet largely unexplored problem in network analysis. To formalize this, w…
A spectral-based framework for hypothesis testing in populations of networks
Li Chen, Nathaniel Josephs, Lizhen Lin +2
In this paper, we propose a new spectral-based approach to hypothesis testing for populations of networks. The primary goal is to develop a test to determine whether two given samp…
Hypothesis testing for populations of networks
Li Chen, Jie Zhou, Lizhen Lin
It has become an increasingly common practice for scientists in modern science and engineering to collect samples of multiple network data in which a network serves as a basic data…
Change-point detection in dynamic networks via graphon estimation
Zifeng Zhao, Li Chen, Lizhen Lin
We propose a general approach for change-point detection in dynamic networks. The proposed method is model-free and covers a wide range of dynamic networks. The key idea behind our…
