TL; DR: CLIP projects visual embedding to the shared latent space using a linear projection layer. We show that simply fine-tuning this guy (:p) can be a strong alternative to linear probing, prompt tuning and CLIP-adapters, and performs also well on test-time adaptation.

Stay tuned for the code!

ProLIP

We fine-tune the pretrained linear projection layer of the vision encoder with a regularization loss towards the pre-trained weights.
