Incremental Identification of Narx Models by Sparse Grid Approximation

  title={Incremental Identification of Narx Models by Sparse Grid Approximation},
  author={Olaf Kahrs and Marc Brendel and Wolfgang Marquardt},
Nonlinear empirical models are used in various applications. During model-building, five major steps usually have to be carried out: model structure selection, determination of input variables, complexity adjustment of the model, parameter estimation and model validation. These steps have to be repeated until a satisfactory model is found, which can be very time consuming and may require user interaction. This paper proposes an algorithm based on sparse grid function approximation to… CONTINUE READING
