[ICCV23] Prompt-aligned Gradient for Prompt Tuning

We present Prompt-aligned Gradient, dubbed ProGrad, to prevent prompt tuning from forgetting the the general knowledge learned from VLMs. In particular, ProGrad only updates the prompt whose gradient is aligned (or non-conflicting) to the “general direction”, which is represented as the gradient of the KL loss of the pre-defined prompt prediction. Extensive experiments demonstrate the stronger few-shot generalization ability of ProGrad over state-of-the-art prompt tuning methods.

The codes are organized into two folders:

1. Dassl.ProGrad.pytorch is the modified toolbox of Dassl.pytorch. 2. ProGrad.public. To get the results in our paper, follow the README.md under ProGrad.public/ to set the environment.
