What are the common mistakes in learning rate scheduling?

What are the common mistakes in learning rate scheduling?

Common mistakes include using a constant learning rate, not adjusting it based on validation performance, and ignoring the warm-up phase.

Can you explain why a constant learning rate is a mistake?

A constant learning rate can lead to suboptimal convergence, as it may be too high or too low for different stages of training.

What is the warm-up phase?

The warm-up phase gradually increases the learning rate from a small value to the initial learning rate, helping stabilize training.

How can I effectively adjust the learning rate during training?

You can use techniques like learning rate schedules, adaptive learning rates, or monitor validation loss to adjust it dynamically.
