One-Way Matching of Datasets with Low Rank Signals
Shuxiao Chen, Sizun Jiang, Zongming Ma +2
We study one-way matching of a pair of datasets with low rank signals. Under a stylized model, we first derive information-theoretic limits of matching under a mismatch proportion…
Community Detection with Contextual Multilayer Networks
Zongming Ma, Sagnik Nandy
In this paper, we study community detection when we observe sparse networks and a high dimensional covariate matrix, all encoding the same community structure among subject…
Global and Individualized Community Detection in Inhomogeneous Multilayer Networks
Shuxiao Chen, Sifan Liu, Zongming Ma
In network applications, it has become increasingly common to obtain datasets in the form of multiple networks observed on the same set of subjects, where each network is obtained…
Nonconvex Matrix Completion with Linearly Parameterized Factors
Ji Chen, Xiaodong Li, Zongming Ma
Techniques of matrix completion aim to impute a large portion of missing entries in a data matrix through a small portion of observed ones. In practice including collaborative filt…
Testing Equivalence of Clustering
Chao Gao, Zongming Ma
In this paper, we test whether two datasets share a common clustering structure. As a leading example, we focus on comparing clustering structures in two independent random samples…
Minimax Rates in Network Analysis: Graphon Estimation, Community Detection and Hypothesis Testing
Chao Gao, Zongming Ma
This paper surveys some recent developments in fundamental limits and optimal algorithms for network analysis. We focus on minimax optimal rates in three fundamental problems of ne…
