Callbacks, such as early stopping and model checkpoints, are critical for efficient model training. An effective early stopping setup can significantly reduce training time by preventing unnecessary epochs when improvement stalls. Real-world applications indicate that proper training management using callbacks often leads to substantial gains in model performance and speed.
The use of learning rate schedulers to adaptively change learning rates during training reflects current trends in optimizing neural network training. Recent studies have shown that dynamic adjustment of learning rates can accelerate convergence and improve final model accuracy, representing a vital practice for modern AI developers.
Callbacks enable actions like logging, early stopping, and adjusting learning rates during training.
