A new research paper published on arXiv questions the reliance on semantic content in vision-language anomaly detection models. The study suggests that the performance gains in few- and full-shot detectors are primarily due to the "effective scale" of text descriptions rather than their linguistic meaning. Experiments across various datasets and model architectures indicate that text embeddings contribute to performance through their difference vectors and geometric arrangements, with scale-matched random anchors performing comparably to actual prompts.
