A Computer Algebra System for R: Macaulay2 and the m2r Package

open access: yesJournal of Statistical Software, 2020
Algebraic methods have a long history in statistics. Apart from the ubiquitous applications of linear algebra, the most visible manifestations of modern algebra in statistics are found in the young field of algebraic statistics, which brings tools from ...

Nontrivial solutions of linear functional equations: methods and examples [PDF]

open access: yesOpuscula Mathematica, 2015
For a wide class of linear functional equations the solutions are generalized polynomials. The existence of non-trivial monomial terms of the solution strongly depends on the algebraic properties of some related families of parameters.

Algebraic Methods for Traffic Flow Densities Estimation

open access: yesCybernetics and Information Technologies, 2013
An estimation approach that allows recovering of the traffic state is proposed in this paper. The method used is based on numerical differentiation, which does not need any integration of differential equations and turns out to be quite robust with ...

A Granular Computing Based Classification Method From Algebraic Granule Structure

open access: yesIEEE Access, 2021
Classification, as one of the main task of machine learning, corresponds to the core work of granular computing, namely granulation. Most of granular computing models and related classification methods are uniquely classifying by granule features, but ...

Stochastic Runge–Kutta methods for multi-dimensional Itô stochastic differential algebraic equations

open access: yesResults in Applied Mathematics, 2021
In this paper, we discuss the numerical solutions to index 1 stochastic differential algebraic equations. We introduce a new class of weak second-order stochastic Runge–Kutta methods for finding the numerical approximate solutions to multi-dimensional ...

An Analysis of Fifth and Sixth Graders' Algebraic Thinking about Reverse Fraction Problems

open access: yesJournal of Educational Research in Mathematics, 2020
In light of a growing emphasis on the relationship between fractional knowledge and algebraic thinking, the purpose of this study was to compare algebraic thinking about reverse fraction problems between fifth graders who had not been taught fraction ...
