A New Algorithm for Positive Semidefinite Matrix Completion

open access: yesJournal of Applied Mathematics, 2016
Positive semidefinite matrix completion (PSDMC) aims to recover positive semidefinite and low-rank matrices from a subset of entries of a matrix. It is widely applicable in many fields, such as statistic analysis and system control.

Exponential Family Matrix Completion under Structural Constraints [PDF]

open access: yes, 2015
We consider the matrix completion problem of recovering a structured matrix from noisy and partial measurements. Recent works have proposed tractable estimators with strong statistical guarantees for the case where the underlying matrix is low--rank, and

Background Subtraction via Fast Robust Matrix Completion

open access: yes, 2017
Background subtraction is the primary task of the majority of video inspection systems. The most important part of the background subtraction which is common among different algorithms is background modeling.

Sequential Matrix Completion

open access: yes, 2017
We propose a novel algorithm for sequential matrix completion in a recommender system setting, where the $(i,j)$th entry of the matrix corresponds to a user $i$'s rating of product $j$. The objective of the algorithm is to provide a sequential policy for user-product pair recommendation which will yield the highest possible ratings after a finite time ...

A Combined Low-Rank Matrix Completion and CDBN-LSTM Based Classification Model for Lower Limb Motion Function

open access: yesIEEE Access, 2020
Assessment of lower limb motion function is crucial for clinicians to treat patients effectively. However, diagnosis accuracy is still affected by clinical experience.

Matrix Completion With Covariate Information

open access: yesJournal of the American Statistical Association, 2018
This paper investigates the problem of matrix completion from corrupted data, when additional covariates are available. Despite being seldomly considered in the matrix completion literature, these covariates often provide valuable information for completing the unobserved entries of the high-dimensional target matrix A0. Given a covariate matrix X with

Approximation theory and matrix completions

open access: yesLinear Algebra and its Applications, 2004
The authors start by proving some interesting results in low-dimensional matrix approximation problems. For example, they show that (1) a one-dimensional subspace \({\mathcal L}\) of \(M_n(\mathbb{C})\), the space of \(n\)-by-\(n\) complex matrices, is Chebyshev (that is, every matrix in \(M_n(\mathbb{C})\) has a unique approximant in \({\mathcal L}\))
