Tensorflow -- Learn How to Use Callbacks Efficiently

In doubt about what is the best learning rate for your model? This little guy can help you solve it! Based on a function, you can modify this parameter without having to interrupt model training! Let's look at our code. Well, this callback only needs a single function to work; The function itself needs the actual epoch and learning rate as parameters, but don't worry, your callback captures these values directly from the model.fit
