right here we are going to attach this projection head just to because the dimensionality here I think is like 2048 and we want to do this inner product in a lower dimension of like maybe 256 or so so this these are just multi-layer perceptrons these are just fully connected layers that compress the representation down to that and once we're done with the unsupervised returning we're going to throw those away right and this ResNet is the thing that we really care about now here they claim okay it actually works better and
