WebHow does Keras reduce learning rate? A typical way is to to drop the learning rate by half every 10 epochs. To implement this in Keras, we can define a step decay function and use LearningRateScheduler callback to take the step decay function as argument and return the updated learning rates for use in SGD optimizer.
