Luttrell S P, July 1988, Self-organising multilayer topographic mappings, Proceedings of 2nd International Conference on Neural Networks (San Diego, USA), (, ed. ), vol. , pp. I/93-I/100
We use a minimum distortion measure argument to derive the need for topographic mappings in unsupervised multilayer networks, and we perform some numerical experiments to demonstrate the power of multilayer topographic mappings.
