shouldn't right if it already predicts two things and these are assigned to these two things and then it outputs one more thing it is going to be penalized because it should output three things with no class but it has output one-to-many with a with a class is going to be penalized okay so the this is a pretty pretty cool thing it again it relies on the fact that you have n on both sides but you can make n so large that basically it covers all of the cases so you can make n like 50 so you can detect up to 50 things in a scene
