Hi guys,
I'm trying to build a DeepLearning network which contains a subtraction operation between two layers, and I can't find a way to do that while MATLAB has just an addition operation (additionLayer)?
for more clarification, the equation below discribes the step that I should do:
C = X - AvgPooling(X)
any suggestions guys?

I think maybe you can define a custom layer that implement a layer multiplicated by -1, then use additionLayer to get what you want.
