In this video we look at ways to customize model behavior during training and testing using Keras Callbacks. Specifically we look at ways how to save model during training epochs, using a learning rate scheduler and an example of a simple custom callbacks.

Loss or a cost function is an important concept we need to understand if you want to grasp how a neural network trains itself. We will go over various loss functions in this video such as mean absolute error (a.k.a MAE), mean squared error (a.k.a MSE), log loss or binary cross entropy. After going through theory we will implement these loss functions in python. It is important to go through this implementation as it might be useful during your interviews (if you are targeting a role of a data scientist or a machine learning engineer)
