which is still quite remarkable but I mean that's you get the same thing for a lot of these methods so I don't know I don't know how much different this would be in other methods but certainly it's interesting to look at now they go into one last thing and that is what if we don't know how many clusters there are right if we don't know anything so say so far we have assumed to to have knowledge about the number of ground truth classes the model predictions were valid losing the Hungarian matching algorithm we already saw this in the DET
