model so that's basically you can it's a testament that out of this out of this 85 you can make this 88 uh just by smartly using the information that the model that this model has learned about the data and transferring it to new data so they train an efficient net b7 that's the small model as a teach model then by using the b7 model as the teacher we trained an efficient net l2 model with the unlabeled batch size set to 14 times the labeled batch size and they stress that it's important that you up the batch size
