different minima here we're talking about the student model learning different things and that's what we've discussed already the student model kind of learns to be robust and that's probably a minimum that's fairly far away in weight space at least in in a sort of energy landscape weight space uh might be the case that it needs to actually overcome kind of a a hill here even though the minimum might be close there's lots of research in like how minima are distributed in these weight spaces which i don't want to go into right here
