augment the student uh when you do not date to augment you can immediately see that the accuracy drops and then when you do not augment and also don't use these model noises then the performance drops again and lastly when you use the teacher but you noise the teacher you can see also here the performance is dropping from the original um quite a bit so all of these things kind of contribute and they do much more ablations and they have listed their findings here so using a large teacher model with better performance leads to better results so
