OCSVM-Guided Representation Learning for Unsupervised Anomaly Detection
Researchers propose a novel unsupervised anomaly detection method that directly couples representation learning with One-Class SVM through a custom loss function, addressing limitations in existing reconstruction-based and decoupled approaches. The method demonstrates effectiveness on image corruption benchmarks and clinical brain MRI lesion detection, showing robustness to domain shifts without requiring labeled anomalous data.
