Piecewise approximation and neural networks
Martina Révayová, Csaba Török (2007)
Kybernetika
The paper deals with the recently proposed autotracking piecewise cubic approximation (APCA) based on the discrete projective transformation, and neural networks (NN). The suggested new approach facilitates the analysis of data with complex dependence and relatively small errors. We introduce a new representation of polynomials that can provide different local approximation models. We demonstrate how APCA can be applied to especially noisy data thanks to NN and local estimations. On the other hand,...
Pointwise approximation by Meyer-König and Zeller operators
Xiao-Ming Zeng, Jun-Ning Zhao (2000)
Annales Polonici Mathematici
We study the rate of pointwise convergence of Meyer-König and Zeller operators for bounded functions, and get an asymptotically optimal estimate.

Polynomial chaos in evaluating failure probability: A comparative study
Eliška Janouchová, Jan Sýkora, Anna Kučerová (2018)
Applications of Mathematics
Recent developments in the field of stochastic mechanics and particularly regarding the stochastic finite element method allow to model uncertain behaviours for more complex engineering structures. In reliability analysis, polynomial chaos expansion is a useful tool because it helps to avoid thousands of time-consuming finite element model simulations for structures with uncertain parameters. The aim of this paper is to review and compare available techniques for both the construction of polynomial...
