WebMar 23, 2024 · A Self-Organizing Map was first introduced by Teuvo Kohonen in 1982 and is also sometimes known as a Kohonen map. It is a special type of an artificial neural network, which builds a map of the training data. The map is generally a 2D rectangular grid of weights but can be extended to a 3D or higher dimensional model.
