Generalized ( p , q ) $(p,q)$ -Bleimann-Butzer-Hahn operators and some approximation results

open access: yesJournal of Inequalities and Applications, 2017
The aim of this paper is to introduce a new generalization of Bleimann-Butzer-Hahn operators by using ( p , q ) $(p,q)$ -integers which is based on a continuously differentiable function μ on [ 0 , ∞ ) = R + $[0,\infty)=\mathbb{R}_{+}$ . We establish the

Probability of noise- and rate-induced tipping [PDF]

open access: yes, 2017
We propose an approximation for the probability of tipping when the speed of parameter change and additive white noise interact to cause tipping. Our approximation is valid for small to moderate drift speeds and helps to estimate the probability of false

Best simultaneous Diophantine approximations. I. Growth rates of best approximation denominators [PDF]

open access: yesTransactions of the American Mathematical Society, 1982
This paper defines the notion of a best simultaneous Diophantine approximation to a vector α \alpha in R n R^n with respect to a norm ‖ ⋅ ‖ \left \| \,\cdot \, \right \| on R n R^n .

Rate of approximation results motivated by robust neural network learning

open access: yesAnnual Conference Computational Learning Theory, 1993
The set of functions which a single hidden layer neural network can approximate is increasingly well understood, yet our knowledge of how the approximation error depends upon the number of hidden units, i.e.

Approximation by q-analogue of modified Jakimovski-Leviatan-Stancu type operators

open access: yesDemonstratio Mathematica, 2017
In this paper, we introduce the q-analogue of the Jakimovski-Leviatan type modified operators introduced by Atakut with the help of the q-Appell polynomials.We obtain some approximation results via the well-known Korovkin’s theorem for these operators.We

Rate of Approximation for Modified Lupaş-Jain-Beta Operators

open access: yesJournal of Function Spaces, 2020
The main intent of this paper is to innovate a new construction of modified Lupaş-Jain operators with weights of some Beta basis functions whose construction depends on σ such that σ0=0 and infx∈0,∞σ′x≥1.

Convergence rate of the data-independent P-greedy algorithm in kernel-based approximation [PDF]

open access: yes, 2016
Kernel-based methods provide flexible and accurate algorithms for the reconstruction of functions from meshless samples. A major question in the use of such methods is the influence of the samples locations on the behavior of the approximation, and ...

Pointwise approximation of 2 π/r-periodic functions by matrix operators of their Fourier series with r-differences of the entries

open access: yesDemonstratio Mathematica, 2018
We extend the results of Xh. Z. Krasniqi [Acta Comment. Univ. Tartu. Math., 2013, 17, 89-101] and the authors [Acta Comment. Univ. Tartu. Math., 2009, 13, 11-24] to the case of 2 π/r-periodic functions.

Modified Bernstein–Durrmeyer Type Operators

open access: yesMathematics, 2022
We constructed a summation–integral type operator based on the latest research in the linear positive operators area. We establish some approximation properties for this new operator.
