Szukana fraza: [Abstract = "The right\-hand side \(RHS\) of the NARMA model is reconstructed from nonuniformly spaced \(N\-D\) samples. This is done by approximating the Fourier transform of the RHS. To this end a feedforward neural network is applied as an implementation of a multi\-dimensional interpolating filter in the \(N\-D\) frequency domain. The neural model obtained in this way is smooth and suitable for the purposes of non\-linear control."]
