Communication-efficient Distributed Estimation and Inference for Transelliptical Graphical Models
Pan Xu, Lu Tian, Quanquan Gu
We propose communication-efficient distributed estimation and inference methods for the transelliptical graphical model, a semiparametric extension of the elliptical distribution i…
A Unified Computational and Statistical Framework for Nonconvex Low-Rank Matrix Estimation
Lingxiao Wang, Xiao Zhang, Quanquan Gu
We propose a unified framework for estimating low-rank matrices through nonconvex optimization based on gradient descent algorithm. Our framework is quite general and can be applie…
Communication-efficient Distributed Sparse Linear Discriminant Analysis
Lu Tian, Quanquan Gu
We propose a communication-efficient distributed estimation method for sparse linear discriminant analysis (LDA) in the high dimensional regime. Our method distributes the data of…
High Dimensional Multivariate Regression and Precision Matrix Estimation via Nonconvex Optimization
Jinghui Chen, Quanquan Gu
We propose a nonconvex estimator for joint multivariate regression and precision matrix estimation in the high dimensional regime, under sparsity constraints. A gradient descent al…
