whereas the student behaves like a single model and yeah it's it's a bit of a weird formulation but it's it's true like the teacher the teacher will produce these same uh the label for different pathways through the student if you use dropout and kind of stochastic depth and therefore the student is kind of required to approximate each time each forward pass has a different forward pass through the layers through the connections with dropout and it's forced to approximate that teacher label with all of these
