Primer on Gradients

Learn about gradients and PyTorch's autograd API.

We'll cover the following...

Implementing explanation methods requires basic knowledge of gradients. So before diving deeper into the course, let’s first quickly review the concepts of gradients.

Gradients

Given a function f(x)f(x), where x=(x1,x2,...xd)x = (x_1, x_2, ... x_d) is a dd-dimensional vector, the gradient of f(x)f(x) with respect to xx, i.e., xf(x)\nabla_x f(x), is a ...
