What I like about this paper is that it translates mathematical scribbles into human language. For example (pictured) the author is here indicating parts of the equation and saying "you take the weights and you just add noise." That's nice. It's explaining why some part of an equation is in there, and it helps viewers understand that the mathematics is just a way for researchers to say some very ordinary things. "What if you fiddled with this value?" "Try turning up the input volume." "Make it respond to the frequency." Whatever.
