Abstract

A comparative empirical study is presented using different cost functions designed to reduce the imbalanced class influence in the training data. This work is focused in the learning and classification process by using perceptron multilayer and radial basis functions neural networks. This artificial neural networks were trained by means of the back-propagation algorithm in batch mode using two class databases.
