Early stopping halts optimization when a validation metric fails to improve for a specified number of epochs. It limits training before the model memorizes data instead of learning patterns that generalize to unseen examples. section 8.1.1
Use early stopping to balance training progress and generalization:
- Training for more epochs can improve learning up to a point; continued training may increase overfitting. section 8.1.1
- Monitor a validation metric and interrupt optimization after its improvement stops for the chosen interval. section 8.1.1
Training with a validation limit
A model improves on training data while its validation performance stops improving. Early stopping ends training at that point rather than allowing additional epochs that could encourage memorization. section 8.1.1
