Factorization of Matrix Polynomials with Symmetries [PDF]

open access: yesSIAM Journal on Matrix Analysis and Applications, 1994
This paper presents a detailed study of the factorizations of matrix polynomials with symmetries. It begins with defining the key properties of matrix polynomials to be discussed: selfadjoint, symmetric, general rank, generally invertible, etc. Then representations of factorizations of various matrix polynomials are presented in detail.

Graph Sparse Nonnegative Matrix Factorization Algorithm Based on the Inertial Projection Neural Network

open access: yesComplexity, 2018
We present a novel method, called graph sparse nonnegative matrix factorization, for dimensionality reduction. The affinity graph and sparse constraint are further taken into consideration in nonnegative matrix factorization and it is shown that the ...

Optimizing and Factorizing the Wilson Matrix

open access: yesThe American Mathematical Monthly, 2022
The Wilson matrix, W, is a 4 × 4 unimodular symmetric positive definite matrix of integers that has been used as a test matrix since the 1940’s, owing to its mild ill-conditioning. We ask how close W is to being the most ill-conditioned matrix in its class, with or without the requirement of positive definiteness.

Transductive Nonnegative Matrix Tri-Factorization

open access: yesIEEE Access, 2020
Nonnegative matrix factorization (NMF) decomposes a nonnegative matrix into the product of two lower-rank nonnegative matrices. Since NMF learns parts-based representation, it has been widely used as a feature learning component in many fields.
