Below is an example of early stopping used while training. Checkpoint is created when the validation loss decreases. The training is stopped when we see no improvement in the validation loss after the given patience.
WebEarly stopping is a term used in reference to machine learning when discussing the prevention of overfitting a model to data. How does one determine how long to train on a data set, balancing how accurate the model is with how well it generalizes?
