[IJCV2024] Progressive Visual Prompt Learning with Contrastive Feature Re-formation

1. We propose a novel structure called Progressive Visual Prompt (ProVP). This design aims to strengthen the interaction among prompts from adjacent layers, thereby enabling more effective propagation to deeper layers.
2. We further introduce a contrastive feature reformation technique to address the generalization deterioration problem in training learnable prompts，whcih prevents significant deviations of prompted visual features from the fixed CLIP visual feature distribution.
3. This combined method, ProVP-Ref, is evaluated across 11 image datasets and achieves state-of-the-art results on 7/11 datasets in both few-shot learning and base-to-new generalization settings.

The codes are organized into two folders:

1. Dassl is the modified toolbox of Dassl.pytorch which supports the implementation of ProVP
2. ProVP.
