Community Detection for Hypergraph Networks via Regularized Tensor Power Iteration
Zheng Tracy Ke, Feng Shi, Dong Xia
To date, social network analysis has been largely focused on pairwise interactions. The study of higher-order interactions, via a hypergraph network, brings in new insights. We stu…

Statistical Inferences of Linear Forms for Noisy Matrix Completion
Dong Xia, Ming Yuan
We introduce a flexible framework for making inferences about general linear forms of a large matrix based on noisy observations of a subset of its entries. In particular, under mi…

Normal Approximation and Confidence Region of Singular Subspaces
Dong Xia
This paper is on the normal approximation of singular subspaces when the noise matrix has i.i.d. entries. Our contributions are three-fold. First, we derive an explicit representat…
