Optimizer apply_gradients
WebMay 29, 2024 · The tape.gradient function: this allows us to retrieve the operations recorded for automatic differentiation inside the GradientTape block. Then, calling the optimizer method apply_gradients, will apply the optimizer's update rules to each trainable parameter. Weboptimizer.apply_gradients(zip(gradients, model.trainable_variables)) performs the parameter updates in the model. And that’s it! This is a rough simulation of the classic fit function provided by Keras but notice that we now have the flexibility to control how we want the parameter updates to take place in our model among many other things.
