چکیده
This paper describes the concepts of Strictly Positive Definite, Universal, Integrally C0-Universal for Gaussian kernel on a Hilbert space. As consequence we obtain similar characterization an important family kernels studied and developed by Schoenberg also spatial-time popular in geostatistics, Gneiting class, its generalizations. Either using techniques, or direct spaces, characterize same defined real hyperbolic

compactifications and function spaces on weighted semigruops
chapter one is devoted to a moderate discussion on preliminaries, according to our requirements. chapter two which is based on our work in (24) is devoted introducting weighted semigroups (s, w), and studying some famous function spaces on them, especially the relations between go (s, w) and other function speces are invesigated. in fact this chapter is a complement to (32). one of the main fea...
15 صفحه اولHilbert Spaces Induced by Toeplitz Covariance Kernels
We consider the reproducing kernel Hilbert space Hμ induced by a kernel which is obtained using the Fourier-Stieltjes transform of a regular, positive, finite Borel measure μ on a locally compact abelian topological group Γ. Denote by G the dual of Γ. We determine Hμ as a certain subspace of the space C0(G) of all continuous function on G vanishing at infinity. Our main application is calculati...
متن کاملPoisson kernels of half–spaces in real hyperbolic spaces
We provide an integral formula for the Poisson kernel of half-spaces for Brownian motion in real hyperbolic space Hn. This enables us to find asymptotic properties of the kernel. Our starting point is the formula for its Fourier transform. When n = 3, 4 or 6 we give an explicit formula for the Poisson kernel itself. In the general case we give various asymptotics and show convergence to the Poi...
متن کاملUniversal Kernels on Non-Standard Input Spaces
During the last years support vector machines (SVMs) have been successfully applied in situations where the input space X is not necessarily a subset of R. Examples include SVMs for the analysis of histograms or colored images, SVMs for text classification and web mining, and SVMs for applications from computational biology using, e.g., kernels for trees and graphs. Moreover, SVMs are known to ...
متن کاملOn a Class of Support Vector Kernels Based on Frames in Function Hilbert Spaces
There has been an increasing interest in kernel-based techniques, such as support vector techniques, regularization networks, and gaussian processes. There are inner relationships among those techniques, with the kernel function playing a central role. This article discusses a new class of kernel functions derived from the so-called frames in a function Hilbert space.
