                         present work data assimilation methods based on Kalman filter (KF) 
                         and artificial neural networks are applied to a three-wave model 
                         of auroral radio emissions. A novel data assimilation method is 
                         presented, whereby a multilayer perceptron neural network is 
                         trained to emulate a KF for data assimilation by using 
                         cross-validation. The results obtained render support for the use
