Class SOMTrainer

java.lang.Object

org.simbrain.network.trainers.Trainer

org.simbrain.network.trainers.SOMTrainer

public class SOMTrainer
extends Trainer

A trainer for SOM Networks. Just goes through input data sets input node and updates the SOM Group, which has the training code built in. TODO: Possibly refactor to an "unsupervised trainer" class for use by competitive too, which is similar.
