Hands-On Transfer Learning with Python

Early stopping

As the training for a large neural network proceeds, training errors decrease steadily over time, but as shown in the following figure, validation set errors starts to increase beyond some iterations:

Early stopping: training versus validation error

If the training is stopped at the point where the validation errors start increasing, we can have a model with better generalization performance. This is called early stopping. It's controlled by a patience hyperparameter, which sets the number of times to observe increasing validation set error before training is aborted. Early stopping can be used either alone or in conjunction ...
