Numerical investigation of Differential Biological-Models via GA-Kansa Method Inclusive Genetic Strategy

open access: yes, 2017
In this paper, we use Kansa method for solving the system of differential equations in the area of biology. One of the challenges in Kansa method is picking out an optimum value for Shape parameter in Radial Basis Function to achieve the best result of ...

Univariate Multiquadric Approximation: Reproduction of Linear Polynomials [PDF]

open access: yes, 1990
It is known that multiquadric radial basis function approximations can reproduce low order polynomials when the centres form an infinite regular lattice. We make a start on the interesting question of extending this result in a way that allows the centres to be in less restrictive positions.

MULTIQUADRIC QUASI-INTERPOLATION METHOD FOR FRACTIONAL INTEGRAL-DIFFERENTIAL EQUATIONS

open access: yesJournal of Applied Analysis & Computation
Summary: In this paper, Multiquadric quasi-interpolation method is used to approximate fractional integral equations and fractional differential equations. Firstly, we construct two operators for approximating the Hadamard integral-differential equation based on quasi interpolators, and verify their properties and order of convergence.

Quantile regression with generalized multiquadric loss function

open access: yes
Quantile regression (QR) is now widely used to analyze the effect of covariates on the conditional distribution of a response variable. It provides a more comprehensive picture of the relationship between a response and covariates compared with classical least squares regression.
