Self-organizing maps

A self-organizing map is a model that was proposed for the first time by Willshaw and Von Der Malsburg (in How Patterned Neural Connections Can Be Set Up by Self- Organization, Willshaw, D. J. and Von Der Malsburg, C., Proceedings of the Royal Society of London, B/194, N. 1117, 1976), with the goal of finding a way to describe different phenomena that happen in the brains of many animals.
