python-kerasHow can I implement early stopping using Python and Keras?
Early stopping is a popular technique used to prevent overfitting in deep learning models. It can be implemented using Python and Keras by using the EarlyStopping
callback. This callback monitors the model's performance, and when a chosen metric (e.g. validation loss) no longer improves, the training process is stopped.
Example code
from keras.callbacks import EarlyStopping
es = EarlyStopping(monitor='val_loss', patience=3)
model.fit(X_train, y_train, callbacks=[es], epochs=100)
The code above uses the EarlyStopping
callback to monitor the validation loss of the model. The patience
argument specifies how many epochs to wait before stopping training when the validation loss has not improved.
