Regression assessment of the model based on the experimental planning matrix in composite materials’ analysis problems [PDF]
E3S Web of Conferences, 2021 An automated coefficients calculation of the regression model based on the experimental data in the form of a planning matrix is considered. The calculations are based on polynomial regression with possible consideration of the interaction effects ...

Computing quaternion matrix pseudoinverse with zeroing neural networks
AIMS Mathematics, 2023 In recent years, it has become essential to compute the time-varying quaternion (TVQ) matrix Moore-Penrose inverse (MP-inverse or pseudoinverse) to solve time-varying issues in a range of disciplines, including engineering, physics and computer science ...

Open Journal of Mathematical Optimization, 2021 The M-P (Moore–Penrose) pseudoinverse has as a key application the computation of least-squares solutions of inconsistent systems of linear equations. Irrespective of whether a given input matrix is sparse, its M-P pseudoinverse can be dense, potentially

Approximation of the Nonlinear B-H Curve by Complex Exponential Series
IEEE Access, 2020 The paper presents an accurate and simple method for the approximation of the nonlinear B-H curves using expansion into complex exponential series. The least-squares fit of the model is obtained by the application of the Moore-Penrose pseudoinverse.

Frequency Interpolation of LOFAR Embedded Element Patterns Using Spherical Wave Expansion
International Journal of Antennas and Propagation, 2021 This paper describes the use of spherical wave expansion (SWE) to model the embedded element patterns of the LOFAR low-band array. The goal is to reduce the amount of data needed to store the embedded element patterns.

A parametric framework for multidimensional linear measurement error regression.
PLoS ONE, 2022 The ordinary linear regression method is limited to bivariate data because it is based on the Cartesian representation y = f(x). Using the chain rule, we transform the method to the parametric representation (x(t), y(t)) and obtain a linear regression ...
