Optimization of Data Matrix Completion by Symmetric Weighting Algorithm
四川大学学报. 自然科学版, 2021 Data set matrix is missing in data analysis, data elements can be completed by data matrix, and the efficient completion data matrix algorithm can be optimized and improved from the aspects of algorithm accuracy.

A regularised deep matrix factorised model of matrix completion for image restoration
IET Image Processing, 2022 It has been an important approach of using matrix completion to perform image restoration. Most previous works on matrix completion focus on the low‐rank property by imposing explicit constraints on the recovered matrix, such as the constraint of the ...

Matrix completion discriminant analysis [PDF]
Computational Statistics & Data Analysis, 2015 Matrix completion discriminant analysis (MCDA) is designed for semi-supervised learning where the rate of missingness is high and predictors vastly outnumber cases. MCDA operates by mapping class labels to the vertices of a regular simplex. With c classes, these vertices are arranged on the surface of the unit sphere in c - 1 dimensional Euclidean ...

Non-Linear Matrix Completion for Social Image Tagging
IEEE Access, 2017 In this paper, we address the problem of social image tagging using practical vocabulary for mobile users on the social media. On the social media, images usually have an incomplete or noisy set of social tags provided by the mobile users, and we ...

Low-Rank Matrix Completion via QR-Based Retraction on Manifolds
Mathematics, 2023 Low-rank matrix completion aims to recover an unknown matrix from a subset of observed entries. In this paper, we solve the problem via optimization of the matrix manifold. Specially, we apply QR factorization to retraction during optimization. We devise
