that in this whole mapping the choice of z and z prime are essentially ignored so you can choose different Z or Z Prime you still need to satisfy this mapping so what that means is that the noise source is necessarily ignored when you impose a cycle consistency loss and when you optimize it to is fixed port so that's not good and then there was this augment excite Oakham paper that proposed a way to solve it so you would augment the noise to your architecture but you will also learn so instead of only learning the mapping from A to B
