Signature Kernels

Signature Kernels#

This section covers the signature kernel and its Gram matrix, along with higher-level statistics built on top (scoring rules and MMD). It also covers the library of static kernels on \(\mathbb{R}^d\) which can be supplied as the base kernel lifted by the signature kernel.
