| Abstract | Artificial Neural Network (ANN) is a new approach for data assimilation process. The performance of two feedforward (multilayer perceptron and radial basis function), and two recurrent (Elman and Jordan) ANNs is analized. The Lorenz system under chaotic regime is used as a test problem. These four NNs were trainned for emulating a Kalman filter using cross validation scheme. Multilayer perceptron and Elman ANNs show better results. The results obtained encouraging the application of the ANNs as an assimilation technique. RESUMO: Redes neurais artificiais é uma nova abordagem para assimilação de dados. Neste trabalho é analisado o desempenho de duas redes feedforward (perceptron de múltiplas camadas e função de base radial) e duas redes recorrentes (Elman e Jordan). O sistema de Lorenz sob regime caótico é usado como um problema teste. As redes foram treinadas para emular um filtro de Kalman, usando a técnica de realimentação com validação cruzada. O perceptron de múltiplas camadas e a rede de Elman foram as que obtiveram os melhores desempenhos. Os resultados encorajam a aplicação de redes neurais como uma técnica assimilação. |
