New Nd4j backprop ops for activations #211

merged 8 commits into from Sep 2, 2019


Copy link

commented Aug 31, 2019

Change nd4j ops to use the new(ish?) C++ backprop ops. Also have the DL4J activation functions use them.

Also added ThresholdRelu ops and fixed a few other usages of deprecated methods.

Existing derivative ops and DifferentialFunctionFactory methods have been deprecated but not removed, as there could conceivably be some scenario when you want the derivative without the backprop multiplication. I can delete/update these if its wanted.
