General notes on the general technique of increasing the numebr of slack parameters you have, especially in machine learning. Convex relaxations often hinge upon this.
RJ Liption discusses Arno van den Essen’s incidental work on stabilisation methods of polynomials, which relates. AFAICT, to transfer-function-type stability. Does this connect to the overparmeterisation of rational transfer fucntion analysis I so enjoyed?HaMR16
