Figure 2: Relationship between the target system’s decorrelation time and the optimal spectral radius in an echo state network (ESN)

Caption

The optimal spectral radius increased as the time scale of the target system became longer under both training conditions: (a) fixed training data points and (b) varying training data points, suggesting a guideline for selecting echo state network (ESN) settings.
