Researchers have developed Omni-NegCLIP, a modified version of the CLIP vision-language model designed to better understand negation in text prompts. The model uses a novel contrastive fine-tuning approach that specifically targets the front layers of CLIP's text encoder. This method significantly improves performance on tasks involving presence-based and absence-based negation, while also enhancing general image-text retrieval capabilities. AI
