is there a substraction operation between Deep Learning layers?

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?

Hello ihssane houhou, had you resolved this issue? If yes, how please I need to do it as well.

Hello @Ullah Nadeem

At that time I didn't find a solution so I switched to Python (TensorFlow) witch what I recommand you to do (and it's better if you go for Pytorch instead of TensorFlow)

BTW I just checked again for a subtruction layer in Matlab 2024 and it seems they didn't add it till now

Good luck

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