Dynamical Systems as Temporal Feature Spaces

no code implementations15 Jul 2019 Peter Tino

We quantify richness of feature representations imposed by dynamic kernels and demonstrate that for dynamic kernel associated with cycle reservoir topology, the kernel richness undergoes a phase transition close to the edge of stability.
