## How can you choose an optimal value of the learning rate in gradient descent algorithms?

In this module, you’ll learn what is a loss function, how a machine learning model iteratively reduces loss, and how you can use the ‘learning rate’ hyperparameter to optimize the loss function.

# What is a loss function?

**Loss** is a number that indicates the difference between the model predictions to the actual values (labels). When…
