other so this problem form a high level seems pretty hopeless because you have really given too little information to to tacko it so what we would look at next kind of certain so basically the crucial problem now is like where do we even get any training data like if I don't have any supervised pairs like what do I even train the model on so the the way that people have been doing this is they try to rely on certain invariants that are true for kind of any pairs of distributions and then somehow you could get some meaningful learning
