Abstract
Reservoir Computing (RC) is a promising general framework for processing high bit-rate data streams [1]. The basic idea behind RC is the expansion of an original complex problem (input data), onto the higher dimensional phase space of the reservoir, in which it is expected that a simple linear separation can solve the problem formulated by the input data. Standard reservoirs are composed of a large number of randomly interconnected nodes. It has been recently shown that a single nonlinear node with delayed feedback substitutes an entire network of nodes maintaining similar processing power [1]. By defining virtual nodes as delayed states that reside in the delay line, it is enough to have only one hardware node in the setup.
