Reimagining Anomalies: What If Anomalies Were Normal?

no code implementations22 Feb 2024 Philipp Liznerski, Saurabh Varshneya, Ece Calikus, Sophie Fellenz, Marius Kloft

Deep learning-based methods have achieved a breakthrough in image anomaly detection, but their complexity introduces a considerable challenge to understanding why an instance is predicted to be anomalous.

Anomaly Detection counterfactual

Wisdom of the Contexts: Active Ensemble Learning for Contextual Anomaly Detection

no code implementations27 Jan 2021 Ece Calikus, Slawomir Nowaczyk, Mohamed-Rafik Bouguelia, Onur Dikmen

Furthermore, the results support our initial hypothesis that there is no single perfect context that successfully uncovers all kinds of contextual anomalies, and leveraging the "wisdom" of multiple contexts is necessary.
