abstract = "Early stopping typically stops training the first time
validation fitness disimproves. This may not be the
best strategy given that validation fitness can
subsequently increase or decrease. We examine the
effects of stopping subsequent to the first
disimprovement in validation fitness, on symbolic
regression problems. Stopping points are determined
using criteria which measure generalisation loss and
training progress. Results suggest that these criteria
can improve the generalistion ability of symbolic
regression functions evolved using Grammar-based GP.",
