Relative error of validation \(err(\hat{\mathbf{X }}')\) for SINAR on visible variable x of the extended Hénon system for two different values of c with different memory depths p on the x axis. The prediction accuracy improves with increasing memory depth. Results based on SINAR with \(\lambda = 0\). As parameters in the extended Hénon system, we chose \(a = 1.3, b = 0.3\) and \(c = 0.3\) (left) resp. \(c = 0.03\) (right). For every value of p, the same 80 time steps were taken into account for the reconstruction error
