| 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 are analyzed. The Lorenzs system under chaotic regime is used as a test problem. These four ANNs were trained for emulating a Kalman filter using cross validation scheme. Multilayer Perceptron and Elman ANNs show better results among ANNs tested. The results obtained encouraging the application of the ANNs as na assimilation technique. Rede Neural Artificial é uma nova abordagem para assimilação de dados. Neste artigo 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 validação cruzada. O perceptron de múltiplas camadas e a rede de Elman apresentaram melhor desempenho entre as redes testadas. Os resultados encorajam a investigação de redes neurais como uma técnica para assimilação de dados em previsão de tempo operacional.. |
