and B to a you will learn an encoder of each of the noise source not the similar to how an encoder is used in a variational method and it's actually pretty interesting so the way that you would go is I have some ground Shu image a and I have then what I'm going to say is that my ground truth image a would comes from a corresponding B and it's corresponding noise sauce za and then I would have this blue arrow which is a network that infer what's the a it is so basically I'm trying to infer what Zee produce my a and I'm going to
