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…
Sparse GCA and Thresholded Gradient Descent
Sheng Gao, Zongming Ma
Generalized correlation analysis (GCA) is concerned with uncovering linear relationships across multiple datasets. It generalizes canonical correlation analysis that is designed fo…
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…
Sample canonical correlation coefficients of high-dimensional random vectors with finite rank correlations
Zongming Ma, Fan Yang
Consider two random vectors and of the forms $\widetilde{\mathbf x}=A\mathbf z+\mathbf C_1^{1/2}\mat…
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…
Community detection in sparse latent space models
Fengnan Gao, Zongming Ma, Hongsong Yuan
We show that a simple community detection algorithm originated from stochastic blockmodel literature achieves consistency, and even optimality, for a broad and flexible class of sp…
