basically you would need to learn the product of these two different possibilities B 1 2 A 1 B 2 2 a 2 B so how many like totally possible solutions are there to this problem if we just use marginal matching yeah so basically each direction there are two possibilities and then if you multiply them together there are four possible solutions in this problem and they are basically totally ambiguous so this is one of the thing that we are seeing here is you can have your objective function that induce a really large solution set really in
