Method Detail

doLearningEpoch

public void doLearningEpoch(DataSet trainingSet)

Description copied from class: SupervisedLearning

This method implements basic logic for one learning epoch for the supervised learning algorithms. Epoch is the one pass through the training set. This method iterates through the training set and trains network for each element. It also sets flag if conditions to stop learning has been reached: network error below some allowed value, or maximum iteration count

Overrides:
