Use of operator defect identities in multi-channel signal plus residual-analysis via iterated products and telescoping energy-residuals: Applications to kernels in machine learning

Palle E. T. Jorgensen, Myung-Sin Song, James F. Tian

We present a new operator theoretic framework for analysis of complex systems with intrinsic subdivisions into components, taking the form of "residuals" in general, and "telescopi…

Factorization of positive definite kernels. Correspondences: -algebraic and operator valued context vs scalar valued kernels

Palle E. T. Jorgensen, James Tian

We introduce and study a class of generalized positive definite kernels of the form , where is a unital $C^{…

Hilbert space-valued Gaussian processes, and quantum states

Palle E. T. Jorgensen, James Tian

We offer new results and new directions in the study of operator-valued kernels and their factorizations. Our approach provides both more explicit realizations and new results, as…

New duality in choices of feature spaces via kernel analysis

Palle E. T. Jorgensen, James Tian

We present a systematic study of the family of positive definite (p.d.) kernels with the use of their associated feature maps and feature spaces. For a fixed set , generalizing…

From Classical to Quantum: Polymorphisms in Non-Commutative Probability

Palle E. T. Jorgensen, James Tian

We present a parallel between commutative and non-commutative polymorphisms. Our emphasis is the applications to conditional distributions from stochastic processes. In the classic…

Operator-Valued Kernels, Machine Learning, and Dynamical Systems

Palle E. T. Jorgensen, James Tian

In the context of kernel optimization, we prove a result that yields new factorizations and realizations. Our initial context is that of general positive operator-valued kernels. W…
