okay here is it in the upper half or the lower half of my classes okay cool it's in the upper half okay here is in the upper half or the lower half and so on and you learn all to predict all of these junctions right here and that's going to end up you with you having to predict it less now of course you are constrained you impose a very big prior on the class distribution classes are an independently anymore namely if two classes here are in the same subtree that means that they are going to be predicted their predictions are going to
