UniOD: A Single Model for Zero‑Training Cross‑Domain Anomaly Detection

UniOD introduces a universal outlier detection model that leverages historical labeled datasets to train one deep graph‑neural‑network‑based model, enabling plug‑and‑play anomaly detection on unseen domains without any retraining, and is backed by theoretical guarantees and extensive cross‑domain experiments.
