Stop training early and keep the best Keras weights
Use EarlyStopping and ModelCheckpoint to halt training when validation loss plateaus and restore the best-performing weights automatically.

kerasStop Overfitting Fast: Using EarlyStopping and ModelCheckpoint in Keras
Stop training before your model overfits with Keras’ EarlyStopping and ModelCheckpoint. Learn how to set up the callbacks, combine them correctly, and verify the best‑saved model with a concrete MNIST example.
Keras fit() lacks native timeout parameter
The Keras fit() method provides no built-in timeout mechanism, requiring users to add custom callbacks to stop training after a set duration. Current callbacks such as EarlyStopping monitor validation loss but cannot enforce time-based stopping, and manual KeyboardInterrupt handling may leave the model in an inconsistent state if weights are not checkpointed
