Numerical performance of the matrix pencil algorithm computing the greatest common divisor of polynomials and comparison with other matrix-based methodologies

open access: yesJournal of Computational and Applied Mathematics, 1996
The problem of finding the greatest common divisor (GCD) of a given polynomial set has interested mathematicians for a very long time and has widespread applications in several branches of control theory, matrix theory, statistics, network theory.

Group-theoretic algorithms for matrix multiplication [PDF]

open access: yes, 2005
We further develop the group-theoretic approach to fast matrix multiplication introduced by Cohn and Umans, and for the first time use it to derive algorithms asymptotically faster than the standard algorithm.

Wireless Sensor Network Localization via Matrix Completion Based on Bregman Divergence

open access: yesSensors, 2018
One of the main challenges faced by wireless sensor network (WSN) localization is the positioning accuracy of the WSN node. The existing algorithms are arduous to use for dealing with the pulse noise that is universal and ineluctable in practical ...

Quantum-inspired algorithms in practice [PDF]

open access: yesQuantum, 2020
We study the practical performance of quantum-inspired algorithms for recommendation systems and linear systems of equations. These algorithms were shown to have an exponential asymptotic speedup compared to previously known classical methods for ...

The improved FASTmrEMMA and GCIM algorithms for genome-wide association and linkage studies in large mapping populations

open access: yesCrop Journal, 2020
Owing to high power and accuracy and low false positive rate in our multi-locus approaches for genome-wide association studies and linkage analyses, these approaches have attracted considerable attention in plant and animal genetics.

Exploring corner transfer matrices and corner tensors for the classical simulation of quantum lattice systems [PDF]

open access: yes, 2012
In this paper we explore the practical use of the corner transfer matrix and its higher-dimensional generalization, the corner tensor, to develop tensor network algorithms for the classical simulation of quantum lattice systems of infinite size.

Investigating the feature extraction capabilities of non-negative matrix factorisation algorithms for black-and-white images [PDF]

open access: yesITM Web of Conferences
Nonnegative matrix factorisation (NMF) is a class of matrix factorisation methods to approximate a nonnegative matrix as a product of two nonnegative matrices.

Randomized Matrix Decompositions Using R

open access: yesJournal of Statistical Software, 2019
Matrix decompositions are fundamental tools in the area of applied mathematics, statistical computing, and machine learning. In particular, low-rank matrix decompositions are vital, and widely used for data analysis, dimensionality reduction, and data ...
