Empirical Evaluation of Four Tensor Decomposition Algorithms [PDF]

open access: yes, 2007
Higher-order tensor decompositions are analogous to the familiar Singular Value Decomposition (SVD), but they transcend the limitations of matrices (second-order tensors).

Reseaech on identification of caving coal and rock traits

open access: yesGong-kuang zidonghua, 2017
In order to recognize caving coal and rock traits in fully mechanized caving face, an identification method based on continuous wavelet transform and improved singular value decomposition (SVD) was proposed.

Two-Channel Information Fusion Weak Signal Detection Based on Correntropy Method

open access: yesApplied Sciences, 2022
In recent years, as a simple and effective method of noise reduction, singular value decomposition (SVD) has been widely concerned and applied. The idea of SVD for denoising is mainly to remove singular components (SCs) with small singular value (SV ...

Very Large-Scale Singular Value Decomposition Using Tensor Train Networks [PDF]

open access: yes, 2014
We propose new algorithms for singular value decomposition (SVD) of very large-scale matrices based on a low-rank tensor approximation technique called the tensor train (TT) format. The proposed algorithms can compute several dominant singular values and

A Novel Watermarking Method using Hadamard Matrix Quantization

open access: yesJournal of ICT Research and Applications, 2020
One of the most used watermarking algorithms is Singular Value Decomposition (SVD), which has a balanced level of imperceptibility and robustness. However, SVD uses a singular matrix for embedding and two orthogonal matrices for reconstruction, which is ...

A Star Sensor On-Orbit Calibration Method Based on Singular Value Decomposition

open access: yesSensors, 2019
The navigation accuracy of a star sensor depends on the estimation accuracy of its optical parameters, and so, the parameters should be updated in real time to obtain the best performance. Current on-orbit calibration methods for star sensors mainly rely

Early stopping for statistical inverse problems via truncated SVD estimation [PDF]

open access: yes, 2018
We consider truncated SVD (or spectral cut-off, projection) estimators for a prototypical statistical inverse problem in dimension $D$. Since calculating the singular value decomposition (SVD) only for the largest singular values is much less costly than
