N-Dimensional Principal Component Analysis [PDF]

open access: yes, 2010
In this paper, we first briefly introduce the multidimensional Principal Component Analysis (PCA) techniques, and then amend our previous N-dimensional PCA (ND-PCA) scheme by introducing multidirectional decomposition into ND-PCA implementation.

Singular spectrum analysis for effective feature extraction in hyperspectral imaging [PDF]

open access: yes, 2014
As a very recent technique for time series analysis, Singular Spectrum Analysis (SSA) has been applied in many diverse areas, where an original 1D signal can be decomposed into a sum of components including varying trends, oscillations and noise ...

The General Linear Model and the Generalized Singular Value Decomposition [PDF]

open access: yes, 2009
The general linear model with correlated error variables can be transformed by means of the generalized singular value decomposition to a very simple model (canonical form) where the least squares solution is obvious.

Singular random matrix decompositions: distributions. [PDF]

open access: yes, 2002
Assuming that Y has a singular matrix variate elliptically contoured distribution with respect to the Hausdorff measure, the distributions of several matrices associated to QR, modified QR, SV and Polar decompositions of matrix Y are determined, for ...

Robust Damage Detection and Localization Under Complex Environmental Conditions Using Singular Value Decomposition-based Feature Extraction and One-dimensional Convolutional Neural Network

open access: yesChinese Journal of Mechanical Engineering, 2023
Ultrasonic guided wave is an attractive monitoring technique for large-scale structures but is vulnerable to changes in environmental and operational conditions (EOC), which are inevitable in the normal inspection of civil and mechanical structures. This

Fast-Fourier-Transform Enhanced Progressive Singular-Value-Decomposition Algorithm in Double Diagnostic Window Frame for Weak Arc Fault Detection

open access: yesIEEE Access, 2022
In this study, a novel method that progressively applies the fastest form of singular-value decomposition (SVD) to extract nonperiodic arc-fault features is proposed in order to pursue a competent solution for AC weak arc fault detection.

Singular random matrix decompositions: Jacobians. [PDF]

open access: yes, 2002
For a singular random matrix Y, we find the Jacobians associated with the following decompositions; QR, Polar, Singular Value (SVD), L'U, L'DM and modified QR (QDR).

Gearbox Status Recognition based on TMD-SVD and POS-BP Networks Under Strong Interference

open access: yesJixie chuandong, 2021
The vehicle gearbox has a bad working environment and the fault mode is difficult to identify. On the basis of existing methods, a method based on two-layer-mode decomposition (TMD) and singular value decomposition (SVD) is proposed, combined with ...
