Nonlinear System Identification Using Quasi-ARX RBFN Models with a Parameter-Classified Scheme

Figure 7

Histograms of the simulated errors. The horizontal coordinate in each subfigure denotes the simulated error of the model, whose elements are binned into 10 equally spaced containers. Four models are trained by using both short (a) and long (b) training sequences, then the simulated performance variation can be investigated by comparison.
