Szukana fraza: [Abstract = "The proposed systems are a combination of data preprocessing methods, genetic algorithms and the Levenberg\?Marquardt \(LM\) algorithm used for learning feed forward and recurrent neural networks. The initial weights and biases of neural networks chosen by the use of a genetic algorithm are then tuned with an LM algorithm. The evaluation is made on the basis of accuracy and complexity criteria. The main advantage of proposed systems is the elimination of random selection of the network weights and biases, resulting in increased efficiency of the systems."]
