Simultaneous design and training of ontogenic neural network classifiers

The use of neural networks in pattern classification is a relatively recent phenomena. In some instances the nonparametric neural network approach has demonstrated significant advantages over more conventional methods. However, certain of the drawbacks of neural networks have led to interest in the augmentation of the neural network approach with such supporting tools as genetic algorithms (e.g. in support of neural network training). In this paper, the authors take yet a further step. Specifically, they present an approach for the simultaneous design and training of neural networks by means of a tailored genetic algorithm. They then demonstrate its employment on the problem of the classification of firms with regard to future fiscal well-being (i.e. are they likely to fail or survive). The resulting ontogenic neural network exhibits, they believe, some particularly attractive characteristics.
