Looking at the theory as a whole it’s a very small minority.
I’m trying to think if it’s 0 percent outside of backprop…
Arguably high school math gets you quite a bit of understanding. After that in descending order I’d guess Linear Algebra, Statistics/Probability, Basic Calculus, Partial Derivatives…
In other words it’s not all or nothing. The easiest stuff gets you a lot of bang for your buck.
From what I’ve seen it’s a small percentage, and there’s no reason for most people to be put off by it.
Everyone come on in the water is fine.
