A characterization of the extended best φ-approximation operator
(Taylor & Francis, 2011-05)
Given an non necessarily linear operator T defined from an Orlicz space L φ′(Ω, , μ) into itself, where φ′ denote the derivative of a strictly convex function φ, we give necessary and sufficient conditions on T assuring ...

Best local weighted approximation: an approach with abstract seminorms
(Michigan state university press, 2020-02)
In this paper, we extend results given by Z´o and Cuenya in 2007 about a general approach to problems of best vector-valued approximation on small regions from a finite dimensional subspace of polynomials of some degree. ...
Activation function study for wavelet network
(1997-12-01)
The main purpose of this paper is to investigate theoretically and experimentally the use of family of Polynomial Powers of the Sigmoid (PPS) Function Networks applied in speech signal representation and function approximation. ...
