Restricted Riemannian geometry for positive semidefinite matrices
A. Martina Neuman, Yuying Xie, Qiang Sun
We introduce the manifold of {\it restricted} positive semidefinite matrices of fixed rank , denoted . The manifold itself is an open and dense submanifo…
Manifold Denoising by Nonlinear Robust Principal Component Analysis
He Lyu, Ningyu Sha, Shuyang Qin +3
This paper extends robust principal component analysis (RPCA) to nonlinear manifolds. Suppose that the observed data matrix is the sum of a sparse component and a component drawn f…
The EAS approach for graphical selection consistency in vector autoregression models
Jonathan P Williams, Yuying Xie, Jan Hannig
As evidenced by various recent and significant papers within the frequentist literature, along with numerous applications in macroeconomics, genomics, and neuroscience, there conti…
Exact Cluster Recovery via Classical Multidimensional Scaling
Anna Little, Yuying Xie, Qiang Sun
Classical multidimensional scaling is an important dimension reduction technique. Yet few theoretical results characterizing its statistical performance exist. This paper provides…
Joint Estimation of Multiple Dependent Gaussian Graphical Models with Applications to Mouse Genomics
Yuying Xie, Yufeng Liu, William Valdar
Gaussian graphical models are widely used to represent conditional dependence among random variables. In this paper, we propose a novel estimator for data arising from a group of G…
