there will be a set of mappings that go through so the mapping from A to B now it takes a and annoy sauce for B that gives me B and then from this BN a I can try to guess what was the the Z that has generated my original a so that is my encoder to guess Z of a and then finally I would plug in the B they're generated and the Z they are generated and from these two I get back I get back this a prime which supposedly should be close to my original sample so that's all good like it's fairly easy to implement like
