Im currently trying to wrap my head around Automatic Differentiation. I got to the point where i successfully implemented both forward and reverse mode autodiff. Now to my question:
Given a function f i want to compute the second derivative. How to compose forward and reverse mode to achive this. My current understanding is, that you first run one pass of forward-mode and then run the reverse-mode ontop of this pass but this doesnt yield the excpected results.
help would be very appreciated, have a nice day :)
