The convolutions web page (https://course.fast.ai/Lessons/lesson8.html) has a copy of the resources from lesson 3: Neural net foundations (https://course.fast.ai/Lessons/lesson3.html).

There's no reference to the notebook covered in the lesson, which I think is: https://www.kaggle.com/code/jhoward/collaborative-filtering-deep-dive/notebook
