fractal structure. We first give the calculation of fractal dimension of the linear combination of …

Shape preserving -fractal rational cubic splines

N Balasubramani, MGP Prasad, S Natesan - Calcolo, 2020 - Springer
In this article, a new α α-fractal rational cubic spline is introduced with the help of the iterated
function system (IFS) that contains rational functions. The numerator of the rational function …

Fractal Perturbation of the Nadaraya–Watson Estimator

DC Luor, CW Liu - Fractal and Fractional, 2022 - mdpi.com
One of the main tasks in the problems of machine learning and curve fitting is to develop
suitable models for given data sets. It requires to generate a function to approximate the data …

A fractal operator on some standard spaces of functions

P Viswanathan, MA Navascués - Proceedings of the Edinburgh …, 2017 - cambridge.org
Through appropriate choices of elements in the underlying iterated function system, the
methodology of fractal interpolation enables us to associate a family of continuous self …

Fractal interpolation functions for random data sets

DC Luor - Chaos, Solitons & Fractals, 2018 - Elsevier
Abstract Let x 0< x 1< x 2<…< x N and I=[x 0, x N]. Let u be a continuous function defined on
I and let Δ μ={(xk, μ k): k= 0, 1,…, N}, where μ k= u (xk). We establish a fractal interpolation …

Reproducing kernel Hilbert spaces of fractal interpolation functions for curve fitting problems

DC Luor - Fractals, 2022 - World Scientific
In this paper, we show that the spaces of some types of fractal interpolation functions are
reproducing kernel Hilbert spaces with two different types of inner products. Then we apply …

Fractal perturbation of shaped functions: Convergence independent of scaling

N Vijender - Mediterranean Journal of Mathematics, 2018 - Springer
In this paper, we introduce a new class of fractal approximants as a fixed points of the Read–
Bajraktarević operator defined on a suitable function space. In the development of our fractal …
