WebSetting up a Self Organizing Map The principal goal of an SOM is to transform an incoming signal pattern of arbitrary dimension into a one or two dimensional discrete map, and to perform this transformation adaptively in a topologically ordered fashion. We therefore set up our SOM by placing neurons at the nodes of a one or two dimensional lattice.
