New boundaries for positive definite functions

Palle Jorgensen, Feng Tian

With view to applications in stochastic analysis and geometry, we introduce a new correspondence for positive definite kernels (p.d.) and their associated reproducing kernel Hi…

An Infinite Dimensional Analysis of Kernel Principal Components

Palle E. T. Jorgensen, Sooran Kang, Myung-Sin Song +1

We study non-linear data-dimension reduction. We are motivated by the classical linear framework of Principal Component Analysis. In nonlinear case, we introduce instead a new kern…

Superposition, reduction of multivariable problems, and approximation

Palle Jorgensen, Feng Tian

We study reduction schemes for functions of "many" variables into system of functions in one variable. Our setting includes infinite-dimensions. Following Cybenko-Kolmogorov, the o…

Decomposition of Gaussian processes, and factorization of positive definite kernels

Palle Jorgensen, Feng Tian

We establish a duality for two factorization questions, one for general positive definite (p.d) kernels , and the other for Gaussian processes, say . The latter notion, for G…

On reproducing kernels, and analysis of measures

Palle Jorgensen, Feng Tian

Starting with the correspondence between positive definite kernels on the one hand and reproducing kernel Hilbert spaces (RKHSs) on the other, we turn to a detailed analysis of ass…

Martin boundaries of representations of the Cuntz algebra

Palle Jorgensen, Feng Tian

In a number of recent papers, the idea of generalized boundaries has found use in fractal and in multiresolution analysis; many of the papers having a focus on specific examples. P…
