The Anomaly-Aware Vision-Language Adapters (AVA-DINO) framework enhances zero-shot anomaly detection by employing dual-branch adaptation and text-guided dynamic routing to specifically process normal and anomalous patterns. This approach achieves competitive performance across industrial and medical benchmarks, for instance, securing 93.5% Image-AUROC and 92.1% Pixel-AUROC on MVTec-AD.
Key insights
- Normal and anomalous data distributions require distinct feature refinements, suggesting that specialized adaptation pathways are more effective than a uniform transformation for zero-shot anomaly detection.
- Dynamic routing guided by semantic text embeddings can robustly align visual features with appropriate specialized adapters, enhancing the model's ability to differentiate between normal and anomalous patterns.
- Explicit regularization of routing decisions during training is essential for ensuring that specialized adapters learn distinct, interpretable functions and generalize effectively to unseen target domains.
