New AnchorScore method predicts MLLM annotation difficulty using CLIP

Researchers have developed AnchorScore, a novel method utilizing CLIP to predict the difficulty multimodal large language models (MLLMs) face in annotating specific classes. This approach offers a low-cost diagnostic tool to identify classes that MLLMs are least likely to annotate reliably, outperforming other predictors like DINOv2 and ResNet-50. AnchorScore has demonstrated practical applications in optimizing MLLM evaluation, enabling hybrid routing strategies, and prioritizing human review for challenging annotation tasks. AI

IMPACT Provides a low-cost method to identify challenging classes for MLLMs, potentially improving annotation efficiency and accuracy.
