WebSimple Guide to Learning Rate Schedules for Keras Networks¶. When training Python Keras networks using optimizers like stochastic gradient descent (SGD), the learning rate of the network stays constant throughout the training process. This will work in many scenarios. But as we get closer to optima, reducing a learning rate a bit over time can …
