Quiz
01Where can Keras preprocessing layers be placed?
Hint
Preprocessing layers can be part of the model, making preprocessing portable with the saved model.

Hint
Augmentation layers check the 'training' flag and are a no-op during inference.
03Which data formats does model.fit() accept?
Hint
Keras is flexible — fit() accepts NumPy, tf.data, PyTorch DataLoader, PyDataset, and Pandas DataFrames.
