Explicit solutions to correlation matrix completion problems, with an application to risk management and insurance [PDF]
Royal Society Open Science, 2018 We derive explicit solutions to the problem of completing a partially specified correlation matrix. Our results apply to several block structures for the unspecified entries that arise in insurance and risk management, where an insurance company with ...

Apply Optimized Tensor Completion Method by Bayesian CP-Factorization for Image Recovery [PDF]
Control and Optimization in Applied Mathematics, 2021 In this paper, we are going to analyze big data (embedded in the digital images) with new methods of tensor completion (TC). The determination of tensor ranks and the type of decomposition are significant and essential matters.

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 ...

Nonconvex Tensor Relative Total Variation for Image Completion
Mathematics, 2023 Image completion, which falls to a special type of inverse problems, is an important but challenging task. The difficulties lie in that (i) the datasets usually appear to be multi-dimensional; (ii) the unavailable or corrupted data entries are randomly ...
