Mueller matrix differential decomposition [PDF]

open access: yesOptics Letters, 2011
We present a Mueller matrix decomposition based on the differential formulation of the Mueller calculus. The differential Mueller matrix is obtained from the macroscopic matrix through an eigenanalysis. It is subsequently resolved into the complete set of 16 differential matrices that correspond to the basic types of optical behavior for depolarizing ...

Probability Matrix Decomposition Models [PDF]

open access: yesPsychometrika, 1996
In this paper, we consider a class of models for two-way matrices with binary entries of 0 and 1. First, we consider Boolean matrix decomposition , conceptualize it as a latent response model (LRM) and, by making use of this conceptualization ...

Multiresolution matrix factorisation as a compression method for smart meter data

open access: yesThe Journal of Engineering, 2020
The development of a smart grid electricity distribution network with advanced technology in smart metering will produce a massive amount of data. However, the limitation in communication network bandwidth makes it hard to transmit these data to the ...

RMPD: Method for Enhancing the Robustness of Recommendations With Attack Environments

open access: yesIEEE Access, 2021
Personalized item recommendation has become a hot topic research among academic and industry community. But lots of purposeful fraudsters maybe perform different attacks on the recommender system to insert fake ratings, which could reduce the ...

Non-unitary CMV-decomposition

open access: yesSpecial Matrices, 2020
An important decomposition for unitary matrices, the CMV-decomposition, is extended to general non-unitary matrices. This relates to short recurrence relations constructing biorthogonal bases for a particular pair of extended Krylov subspaces.

Orthogonal tucker decomposition using factor priors for 2D+3D facial expression recognition

open access: yesIET Biometrics, 2021
In this article, an effective approach is proposed to recognise the 2D+3D facial expression automatically based on orthogonal Tucker decomposition using factor priors (OTDFPFER).

Decompose Boolean Matrices with Correlation Clustering

open access: yesEntropy, 2021
One of the tasks of data science is the decomposition of large matrices in order to understand their structures. A special case of this is when we decompose relations, i.e., logical matrices.

On decomposition of k-tridiagonal ℓ-Toeplitz matrices and its applications

open access: yesSpecial Matrices, 2015
We consider a k-tridiagonal ℓ-Toeplitz matrix as one of generalizations of a tridiagonal Toeplitz matrix. In the present paper, we provide a decomposition of the matrix under a certain condition.

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.

Amplitude-Preserved Wave Equation: An Example to Image the Gas Hydrate System

open access: yesEnergies, 2021
Natural gas hydrate is an important energy source. Therefore, it is extremely important to provide a clear imaging profile to determine its distribution for energy exploration. In view of the problems existing in conventional migration methods, e.g., the
