The synthesis of the ranked neural networks applying genetic algorithm with the dynamic probability of mutation

Abstract

The real problem connected with the construction of neural networks is to appoint the number of elements (neurons) and the connection structure. The algorithms, which construct the classification networks using ranked layers allow to establish the number of neurons and weights of their connections on the basis of training data set. In this paper, the method of ranked layer construction, using genetic algorithm has been presented. The applying the genetic algorithm leads to obtaining the network with less number of elements, hence the investigated network is of more ability to generalize information. Such a smaller network preserves its given classification property referring to the data of training set. In addition, applying of the genetic algorithm allows to use in the construction process any neuron activation function, e. g. rectangular activation function. This feature results in considerable reduction of the network size.
