Researchers have introduced NegAS, a novel framework designed to enhance out-of-distribution (OOD) object detection in vision-language models (VLMs). NegAS addresses two key challenges: improving attention mechanisms to better identify potential OOD regions and developing a scoring function compatible with VLM probabilistic outputs. The framework utilizes negative labels to guide attention and a sigmoid-based scoring function that distinguishes between in-distribution and OOD instances, showing significant improvements in OOD detection performance on datasets like COCO and OpenImages while maintaining accuracy on in-distribution objects.
