Step 3 - Compute the Gradients
Learn about gradients and how they can be computed and visualized.
We'll cover the following
Introduction to gradients
A gradient is a partial derivative; why partial? Because one computes it with respect to (w.r.t.) a single parameter. Since we have two parameters, b
and w
, we must compute two partial derivatives.
A derivative tells you how much a given quantity changes when you slightly vary some other quantity. In our case, how much does our MSE loss change when we vary each one of our two parameters separately?
