Limitations of the Recall Capabilities in Delay-Based Reservoir Computing Systems

摘要: We analyse the memory capacity of a delay-based reservoir computer with Hopf normal form as nonlinearity and numerically compute linear well higher order recall capabilities. A possible physical realization could be laser external cavity, for which information is fed via electrical injection. task-independent quantification computational capability system done complete orthonormal set basis functions. Our results suggest that even constant readout dimension total dependent on ratio between input period, also called clock cycle, time delay in system. Optimal performance found about 1.6 times cycle.
