cudnnConvolutionBiasActivationForward API Usage


I have a question regarding CUDNN Convolution API cudnnConvolutionBiasActivationForward:

Page 64 mentions this API performs eqn:
y = act ( alpha1 * conv(x) + alpha2 * z + bias )

  1. What is z in this equation ?
  2. How to choose alpha2?
    3.What is zdesc ?

Is there a working example for this API available ?

Thanks in advance !!!

I have the same question.
From the description of alpha2 it is blending the previous output of this layer into the new output.
