Improved Sparse Low-Rank Matrix Estimation
We address the problem of estimating a sparse low-rank matrix from its noisy observation. We propose an objective function consisting of a data-fidelity term and two parameterized non-convex penalty functions. Further, we show how to set the parameters of the non-convex penalty functions, in order to ensure that the objective function is strictly convex. The proposed objective function better e...
متن کاملImproved Deterministic Conditions for Sparse and Low-Rank Matrix Decomposition
In this paper, the problem of splitting a given matrix into sparse and low-rank matrices is investigated. The problem is when and how we can exactly do this decomposition. This problem is ill-posed in general and we need to impose some (sufficient) conditions to be able to decompose a matrix into sparse and low-rank matrices. This conditions can be categorized into two general classes: (a) dete...
متن کاملA Variational Approach for Sparse Component Estimation and Low-Rank Matrix Recovery
We propose a variational Bayesian based algorithm for the estimation of the sparse component of an outliercorrupted low-rank matrix, when linearly transformed composite data are observed. The model constitutes a generalization of robust principal component analysis. The problem considered herein is applicable in various practical scenarios, such as foreground detection in blurred and noisy vide...
متن کاملData-sparse matrix computations Lecture 25: Low Rank + Sparse Matrix Recovery
In the previous lecture, we observed that it is possible to recover a sparse solution to Ax = b by solving a minimization problem involving the 1-norm. In this lecture, we consider a matrix A that can be written as A = L+ S, where L is a low rank matrix and S is a sparse matrix, and seek a method that recovers L and S. We remark that Lecture 26 forms a sequal to these notes and addresses the te...
متن کاملHigh Dimensional Low Rank and Sparse Covariance Matrix Estimation via Convex Minimization
This paper introduces a general framework of covariance structures that can be verified in many popular statistical models, such as factor and random effect models. The new structure is a summation of low rank and sparse matrices. We propose a LOw Rank and sparsE Covariance estimator (LOREC) to exploit this general structure in the high-dimensional setting. Analysis of this estimator shows that...
