Cosine Annealing Schedule

Hard

neural-networks Google NVIDIA Databricks

Cosine annealing decreases the learning rate following a cosine curve over training. Compared to step decay, what advantage does cosine annealing provide, and how does warm restarts extend it?

Multiple Choice

It provides a smooth decay without manual drop-point tuning; warm restarts periodically increase the rate to escape sharp local minima and find flatter solutions It guarantees monotonically decreasing loss, while warm restarts add gradient noise for better exploration It reduces memory usage by pre-computing all learning rates; warm restarts free cached optimizer states It adapts to each parameter individually like Adam; warm restarts reset the per-parameter statistics
