This paper provides a comprehensive review and systematic categorization of current methodologies in self-supervised anomaly detection (SSL-AD). It compares their performance across various data types and anomaly settings, highlighting the critical role of pretext task alignment for optimal results.
Key insights
- Self-supervised learning (SSL) provides a powerful paradigm for anomaly detection by learning robust representations from unlabeled data, addressing data scarcity challenges.
- The choice of self-supervised pretext task is paramount, with different tasks proving more effective for semantic (high-level) versus sensory (low-level) anomalies.
- SSL-AD methods demonstrate strong performance across diverse data modalities, including image, audio, time-series, and graph data, provided domain-specific augmentations and tasks are devised.
