Highlights

Main Contributions

1. Systematical Investigation for the Openness of CLIP: We design the evaluation protocol and two indicators of extensibility and stability.
2. CLIP Feature Space Dissecting: We define inter-modal alignment and intra-modal uniformity, two metrics to measure the quality of representations in contrastive learning for the vision-and-language domain.
3. Retrieval-enhanced prompt engineering (REPE): A simple yet effective method to improve the extensibility and stability of CLIP without fine-tuning.
