Haha, I'm one of the authors, although most of the credit goes to the other author (David Fouhey). Despite being in the form of a joke, this sheet is actually functional, for anyone wondering. Like the one in this post, it's inference only, but for a CNN instead of a transformer. I think someone actually made an excel CNN with backpropagation as well.
