I took a course in my Master's (URV.cat) where we had to do exactly this, implementing backpropagation (fwd and backward passes) from a paper explaining it, using just basic math operations in a language of our choice.

I told everyone this was the best single exercise of the whole year for me. It aligns with the kind of activity that I benefit immensely but won't do by myself, so this push was just perfect.

If you are teaching, please consider this kind of assignments.

P.S. Just checked now and it's still in the syllabus :)

Is that paper publicly available?

Hi! It's not public, it's part of the https://www.urv.cat/en/studies/master/courses/computer-secur... and I've not found it online
