Fractional Norm Regularization Using Truncated Singular Value Decomposition [PDF]

open access: goldIEEE Access, 2022
In a previous work, a solution to the fractional norm regularization (FNR) was discovered in a closed form and an inverse perturbation was adopted as a tool to overcome the ill condition of a matrix whose inverse is required by the fixed-point FNR.

A New Truncation Strategy for the Higher-Order Singular Value Decomposition [PDF]

open access: greenSIAM Journal of Scientific Computing, 2012
We present an alternative strategy for truncating the higher-order singular value decomposition (T-HOSVD). An error expression for an approximate Tucker decomposition with orthogonal factor matrices is presented, leading us to propose a novel truncation strategy for the HOSVD, which we refer to as the sequentially truncated higher-order singular value ...

Truncated singular value decomposition in ripped photo recovery [PDF]

open access: yesITM Web of Conferences, 2021
Singular value decomposition (SVD) is one of the most useful matrix decompositions in linear algebra. Here, a novel application of SVD in recovering ripped photos was exploited. Recovery was done by applying truncated SVD iteratively.

A Trust-Region Method for Solving Truncated Complex Singular Value Decomposition [PDF]

open access: bronzeJournal of Computational Mathematics, 2023
The truncated singular value decomposition has been widely used in many areas of science including engineering, and statistics, etc. In this paper, the original truncated complex singular value decomposition problem is formulated as a Riemannian optimization problem on a product of two complex Stiefel manifolds, a practical algorithm based on the ...

Modified truncated randomized singular value decomposition (MTRSVD) algorithms for large scale discrete ill-posed problems with general-form regularization * [PDF]

open access: green, 2018
In this paper, we propose new randomization based algorithms for large scale linear discrete ill-posed problems with general-form regularization: ${\min} \|Lx\|$ subject to ${\min} \|Ax - b\|$, where $L$ is a regularization matrix.

Truncated singular value decomposition for through‐the‐wall microwave imaging application [PDF]

open access: bronzeIET Microwaves, Antennas & Propagation, 2019
We considered differential through‐the‐wall microwave imaging with different formulations of truncated singular value decomposition (TSVD) method with a non‐anechoic experiment. Previous studies employ TSVD with single transmitting/measuring antenna, while we show how to apply the TSVD in case of a moving linear transmitting/measuring antenna array ...
