U-Statistic Reduction: Higher-Order Accurate Risk Control and Statistical-Computational Trade-Off, with Application to Network Method-of-Moments
Meijia Shao, Dong Xia, Yuan Zhang
U-statistics play central roles in many statistical learning tools but face the haunting issue of scalability. Significant efforts have been devoted into accelerating computation b…
Higher-order accurate two-sample network inference and network hashing
Meijia Shao, Dong Xia, Yuan Zhang +2
Two-sample hypothesis testing for network comparison presents many significant challenges, including: leveraging repeated network observations and known node registration, but with…
Generalized Low-rank plus Sparse Tensor Estimation by Fast Riemannian Optimization
Jian-Feng Cai, Jingyang Li, Dong Xia
We investigate a generalized framework to estimate a latent low-rank plus sparse tensor, where the low-rank tensor often captures the multi-way principal components and the sparse…
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…
Effective Tensor Sketching via Sparsification
Dong Xia, Ming Yuan
In this paper, we investigate effective sketching schemes via sparsification for high dimensional multilinear arrays or tensors. More specifically, we propose a novel tensor sparsi…
