    BTW, I am quite intrigued that the mere existence of a bounded linear functional is sufficient for there to exist a reproducing kernel. As some of you may already be aware, I am computer scientist trying teaching myself a bit of functional analysis in order to better appreciate the mathematical methods I use. Lecture 3: Reproducing Kernel Hilbert Spaces Andrea Caponnetto Description We introduce a particularly useful family of hypothesis spaces called Reproducing Kernel Hilbert Spaces (RKHS) that have a key role in the theory of learning. We first provide the necessary background in functional analysis and then define RKHS using theFile Size: 24KB. In addition, we find relationships for the eigenfunctions and eigenvalues of the reproducing kernel and the operators with homogeneous or nonhomogeneous boundary conditions. These eigenfunctions and eigenvalues are used to compute a series expansion of the reproducing kernel and an orthonormal basis of the reproducing-kernel Hilbert space.

Schur Functions, Operator Colligations, and Reproducing Kernel Pontryagin Spaces. Authors: Alpay, D., Dijksma, A., Rovnyak, J., Snoo, H. de Free Preview. Generalized Schur functions are scalar- or operator-valued holomorphic functions such that certain associated kernels have a finite number of negative squares.

This book develops the Schur functions theory of such functions as characteristic functions of coisometric, isometric, and unitary colligations whose state spaces are reproducing kernel.

The main theme of the first half of this paper rests upon the fact that there is a reproducing kernel Hilbert space of vector valued functions B (X) associated with each suitably restricted matrix.

In this book, Alpay looks at matrix-valued Schur functions and their applications from the unifying point of view of spaces with reproducing kernels.

An H(b) space is defined as a collection of analytic functions that are in the image of an operator. The theory of H(b) spaces bridges two classical subjects, complex analysis and operator theory, which makes it both appealing and by: In functional analysis (a branch of mathematics), a reproducing kernel Hilbert space (RKHS) is a Hilbert space of functions in which point evaluation is a continuous linear y speaking, this means that if two functions and in the RKHS are close in norm, i.e., ‖ − ‖ is small, then and are also pointwise close, i.e., | − | is small for all.
