Beyond Normal References: Discriminative Few-Shot Anomaly Detection
Researchers have developed a new framework called IDEAL for discriminative few-shot anomaly detection. This approach utilizes both normal and anomalous examples as references during inference, unlike previous methods that only used normal references. IDEAL learns intrinsic deviation patterns by first suppressing normal variations and then encoding the remaining deviations into discriminative vectors. This allows the system to generalize to both known and unknown anomalies, outperforming existing methods on eight real-world datasets. AI
