is there a best jumping off point for understanding the ad library - easiest way to get to grips with types/modes and papers that the implementation might closely follow? Mostly want to dig through reverse mode implementations.

dbeacham_ : mayhaps "Functional Differentiation of Computer Programs" by Jerzy Karczmarczuk in 2001 at could be interesting ..

How can I define foo in a more abstract and succinct way? http://lpaste.net/351664

L5 and L6 are the same if I flip x <-> y at the right places

jchia_1 2017-01-26 01:12:15

I mean L4 & L5

I found the answer. g f x = swap . f x . swap

does anyone know how to find out the colour space of an image with JuicyPixels?

ertes 2017-01-26 01:44:42

or alternatively: make it return an image in a certain colour space
