What you’ll practice

Identify the role of a loss, activation or update rule before recalling its expression. Formula recall does not establish that a model is appropriate for a data set.

Where this helps

Reading and implementing machine-learning models with less formula lookup.

Before you start

Use this topic to practice math you have already learned. The examples show the available kinds of recall tasks; this is not a complete textbook chapter. Check the answer form and any stated conditions.

Try a few examples

Real practice. Real progress.

Example 1 of 4

J is differentiable. θ is the parameter vector and η > 0 is the step size.

Choose the exact expression.
