Factorization of positive definite kernels. Correspondences: $C^{*}$ -algebraic and operator valued context vs scalar valued kernels

Palle E. T. Jorgensen, James Tian

We introduce and study a class $M$ of generalized positive definite kernels of the form $K : X \times X \to L (A, L (H))$ , where $A$ is a unital $C^{…

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…
