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, generalize it to a larger class of matrix decomposition models.

Decomposition-Based Correlation Learning for Multi-Modal MRI-Based Classification of Neuropsychiatric Disorders

open access: yesFrontiers in Neuroscience, 2022
Multi-modal magnetic resonance imaging (MRI) is widely used for diagnosing brain disease in clinical practice. However, the high-dimensionality of MRI images is challenging when training a convolution neural network.

Incremental multi‐view correlated feature learning based on non‐negative matrix factorisation

open access: yesIET Computer Vision, 2021
In real‐world applications, large amounts of data from multiple sources come in the form of streams. This makes multi‐view feature learning cost much time when new instances rise incrementally.

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.

An approximating pseudospectral method with state‐dependent coefficient optimization for nonlinear optimal control problem

open access: yesIET Control Theory & Applications, 2023
The approximating sequence Riccati equation method is an efficient approach for solving the nonlinear optimal control problems, but its neglect of nonlinear dynamics and necessary optimality condition makes the control law difficult to satisfy the ...

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 ...

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).

Mean-field density matrix decompositions [PDF]

open access: yesThe Journal of Chemical Physics, 2020
We introduce new and robust decompositions of mean-field Hartree–Fock and Kohn–Sham density functional theory relying on the use of localized molecular orbitals and physically sound charge population protocols. The new lossless property decompositions, which allow for partitioning one-electron reduced density matrices into either bond-wise or atomic ...
