Hi Dejan!



 dejanbatanjac:

Neural net (NN) is a function, right.


Yes, but not necessarily an invertible function.


Can you provide some hints or papers how based on NN we can create inverse neural net INN?


In general, you cannot invert a neural network.  And this is true
not just for unusual edge cases – most typical neural networks
won’t be invertible.
Consider (among others) these two points:
Rectified linear units (f (x) = max (0, x)) are not invertible.
Any linear layer with fewer outputs than inputs in not invertible.
Best.
