Researchers have developed GA2-CLIP, a novel framework designed to enhance the generalization capabilities of Vision-Language Models (VLMs) in video tasks. This plug-and-play method addresses the issue of semantic space narrowing during fine-tuning by incorporating externally supervised prompts. The approach utilizes pre-trained prompts from other datasets as hard tokens, coupled with soft prompt tokens via a learnable mapping layer to prevent overfitting. Additionally, generic attribute anchors, including irrelevant video sets and negative prompts, are employed to preserve the model's ability to generalize to new classes. AI
