tuning sim clear uses this right here which is just it's basically just a classifier on top of the ow foot of the ResNet 50 okay yada yada yada yada this is fine tuning from the input layer of the projection head to fine tune from the first layer of the projection head we have a new encoder function as this which is ResNet followed by fully connected layers and you see they take the resonate 50 output and they ship it through the first projection layer and then there is a task specific classifier now again why I
