Animating neural network training

van der Poel, E; Cloete, I (South African Computer Society (SAICSIT), 1992)

In Artificial Neural Network (ANN) simulation it is usually necessary to examine the behaviour of the ANN and detect problems if they occur. However, due to the large volume and high dimensionality of data generated during ...
The physical correlates of local minima

Wessels, LFA; Barnard, E; Van Rooyen, E (South African Institute of Computer Scientists and Information Technologists, 1991)

The training of neural-net classifiers is often hampered by the occurrence of local minima, which results in the attainment of inferior classification performance. We study the problem of local minima in order to devise ...
Review of mapping neural networks in classification systems

Hing, RL (South African Institute of Computer Scientists and Information Technologists, 1990)

An old approach used in classification systems has been revived by the discovery of new algorithms which use this approach to approximate complex non-linear functions. This approach, known as neurocomputing, classifies ...
