To prevent the net from performing poorly on nontraining (validation, test and unseen data) while learning well on training data, training stops if the validation performance degrades for 6 (default) consecutive epochs. The procedure is called
VALIDATION STOPPING.
Hope this helps.
Thank you for formally accepting my answer

Mu is the momentum constant. To see how it's used lookup the explanation of the Levenberg-Marquardt algorithm.
