supervised compared to to fine tuning on with 100% of the labels so they do a very thorough empirical investigation and yeah I I do appreciate that and they kind of show the same things and here they show the number of layers in the projection head so as you increase the number of layers in the projection head and train from the optimal layer in the middle your performance goes up as you can see but it also this effect is stronger when you have fewer labels right you can see the differences here are greater than the differences here or
