Vector-Valued Kernel Ridge Regression for the Modeling of the Scattering Parameters of a Slotted Ground PCB Structure

This paper presents a preliminary study on the performance of the vector-valued kernel Ridge regression in complex-valued regression problems. The proposed approach is applied for the modeling of the scattering parameters of a slotted ground PCB structure as a function of 2 parameters. The effectiveness of the proposed modeling scheme in terms of both training time and accuracy is assessed for an increasing number of training samples.
