Weighted sparsity and sparse tensor networks for least squares approximation [PDF]

open access: yes, 2023
The approximation of high-dimensional functions is a ubiquitous problem in many scientific fields that is only feasible practically if advantageous structural properties can be exploited. One prominent structure is sparsity relatively to some basis.

The Best Approximation of Generalized Fuzzy Numbers Based on Scaled Metric

open access: yesJournal of Mathematics, 2022
The ongoing study has been vehemently allocated to propound an ameliorated α-weighted generalized approximation of an arbitrary fuzzy number. This method sets out to lessen the distance between the original fuzzy set and its approximation.

Approximation Algorithms for Directed Weighted Spanners [PDF]

open access: yes, 2023
In the pairwise weighted spanner problem, the input consists of a weighted directed graph on n vertices, where each edge is assigned both a cost and a length. Furthermore, we are given k terminal vertex pairs and a distance constraint for each pair.

Approximating Power by Weights [PDF]

open access: yesSSRN Electronic Journal, 2018
Determining the power distribution of the members of a shareholder meeting or a legislative committee is a well-known problem for many applications. In some cases it turns out that power is nearly proportional to relative voting weights, which is very beneficial for both theoretical considerations and practical computations with many members.

On Kantorovich modification of ( p , q ) $( p,q ) $ -Baskakov operators

open access: yesJournal of Inequalities and Applications, 2016
The concern of this paper is to introduce a Kantorovich modification of ( p , q ) $( p,q ) $ -Baskakov operators and investigate their approximation behaviors. We first define a new ( p , q ) $( p,q ) $ -integral and construct the operators.

Approximate BDD Minimization by Weighted A. [PDF]

open access: yes2009 IEEE International Symposium on Circuits and Systems, 2009
Reduced ordered Binary Decision Diagrams (BDDs) are a data structure for efficient representation and manipulation of Boolean functions. They are frequently used in logic synthesis. The size of BDDs depends on a chosen variable ordering, i.e. the size may vary from linear to exponential, and the existence of a polynomial algorithm to approximate the ...

A Constant-Factor Approximation for Weighted Bond Cover [PDF]

open access: yes, 2021
The Weighted ℱ-Vertex Deletion for a class ℱ of graphs asks, weighted graph G, for a minimum weight vertex set S such that G-S ∈ ℱ. The case when ℱ is minor-closed and excludes some graph as a minor has received particular attention but a constant-factor

MODIFIED MODULUS OF SMOOTHNESS AND APPROXIMATION IN WEIGHTED LORENTZ SPACES BY BOREL AND EULER MEANS

open access: yesПроблемы анализа, 2020
Using one-sided Steklov means, we introduce a new modulus of smoothness in weighted Lorentz spaces. The direct and inverse approximation theorem for this modulus of smoothness are proved.

A new construction of Lupaş operators and its approximation properties

open access: yesAdvances in Difference Equations, 2021
The aim of this paper is to study a new generalization of Lupaş-type operators whose construction depends on a real-valued function ρ by using two sequences u m $u_{m} $ and v m $v_{m}$ of functions.
