Some Remarks on Reproducing Kernel Krein Spaces

open access: yes, 1991
The one-to-one correspondence between positive functions and reproducing kernel Hilbert spaces was extended by L. Schwartz to a (onto, but not one-to-one) correspondence between difference of positive functions and reproducing kernel Krein spaces.

Optimal approximation in Hilbert spaces with reproducing kernel functions

open access: yes, 1970
Characterisations of optimal linear estimation rules are given in terms of the reproducing kernel function of a suitable Hilbert space. The results are illustrated by means of three different, useful function spaces, showing, among other things, how ...

The Zero-Removing Property and Lagrange-Type Interpolation Series

open access: yes, 2011
The classical Kramer sampling theorem, which provides a method for obtaining orthogonal sampling formulas, can be formulated in a more general nonorthogonal setting.

Backward shift invariant subspaces in reproducing kernel Hilbert spaces

open access: yes, 2020
In this note, we describe the backward shift invariant subspaces for an abstract class of reproducing kernel Hilbert spaces. Our main result is inspired by a result of Sarason concerning de Branges-Rovnyak spaces (the non-extreme case).

Utilizing Kernel Adaptive Filters for Speech Enhancement within the ALE Framework

open access: yesIranian Journal of Electrical and Electronic Engineering, 2017
Performance of the linear models, widely used within the framework of adaptive line enhancement (ALE), deteriorates dramatically in the presence of non-Gaussian noises. On the other hand, adaptive implementation of nonlinear models, e.g.

Ridge Regression Learning Algorithm in Dual Variables

open access: yes, 1998
In this paper we study a dual version of the Ridge Regression procedure. It allows us to perform non-linear regression by constructing a linear regression function in a high dimensional feature space.
