In machine learning, a prominent paradigm for solving classification and regression problems is that of kernel methods

Since they encode . between input features, they can be employed as a powerful form of data representation, which we explo

In this chapter, we show how the Hilbert-Schmidt and Log-Hilbert-Schmidt distances and inner products can be used to define positive definite kernels, allowing us to apply kernel methods on top of cova
