@noelwelsh Can you recommend a good AD library for Scala?

Yes, need the equivalent of numpy

Breeze covers a reasonable proportion of numpy, but it doesn't yet do tensors - there's currently discussion on github regarding the "best" way to do them...
-
It seems very difficult to retrofit tensors + AD to a system that wasn't designed for them ground-up, in the same way that TF had to reimplement NumPy rather than building on top of it. Especially in a Scala context where I would expect a static compute graph vs tape-based AD.
-
agreed - tensors + AD need to be designed together (with very low overhead for scalars)
