Optional topics: where are their slides?

Hi, I have downloaded all slides for MLS but I found some optional topics don’t have their slides in the downloads. For instance c3w2 slides are missing the principle component analysis part. I also remember in one of the previous courses the back prop optional topic didn’t come with their pages in the course PDF files. Did I miss anything or it was just not uploaded by deep learning.ai?

The PCA materials were added much later, after the courses were created. There are no published slides for this added material.
