  6. PHOCUS Project #240763 Reservoir Computing • Has recently emerged as the generic name in the field of machine learning, that are capable of solving complex classification problems • RC is the mapping of a dynamical input onto a high dimensional state space. The input streams are converted into spatio-temporally distributed states of the reservoir. Specific computations can be realized by a mapping of these distributed states onto output states based on a trained readout. • Three properties are necessary and sufficient conditions for powerful real time computing: • Separation property (SP): SP addresses the amount of separation between the trajectories of internal states of the system that are caused by two different input streams • Approximation property (AP):addresses the capability to distinguish and transform different internal states of the liquid into given target outputs. • Fading Memory: ||u(t)-v(t)|| < d in [0,T], ||f(u)-f(v)|| < e in the same interval
