reorder the things your minimum matching will simplify it will simply swap with it it is it is um if you output the same bird multiple times only one of these is going to be assigned so if if this here is that bird only one of them only this one maybe is going to be assigned to that one and the other ones can't be assigned to that one are forced to be assigned to a different one let's say this one here and are going to incur a loss so you encourage your model to output let's say diverse bounding boxes different bounding boxes for things okay
