How can I reverse my NN? I want to feed the data backwards

Hi, @vadsavin-a Can you go over what you have tried to reverse your network?

Honestly talking, ive tried to do the only one thing: replacing weights and bias matrises. Well, it did not work 🙂

May I see your code?

@ Vadsavin  
If you are using the code I sent you, all you need to do is reverse the layer order (set in the very beginning) and then reverse the weight matrix. I can explain more if this is confusing.  
Best,
