Abstract
A method comprising providing an input signal to at least one input node of a computing reservoir by temporally encoding the input signal by modulating the at least one photonic wave as function of the input signal is described. The method further comprises propagating the at least one photonic wave via passive guided or unguided propagation between discrete nodes of the computing reservoir, in which each discrete node is adapted for passively relaying the at least one photonic wave over the passive interconnections connected thereto. The method also comprises obtaining a plurality of readout signals, in which each readout signal is determined by a non-linear relation to the at least one photonic wave in at least one readout node of the computing reservoir, and combining this plurality of readout signals into an output signal by taking into account a plurality of training parameters.
