arXiv:2606.15280v1 Announce Type: new Abstract: Most existing anomaly detection methods rely on estimating a probability density or learning an enclosing decision boundary, implicitly assuming that normal data occupies a region of non-zero volume in the ambient space. In contrast, structural anomaly detection considers data that lies near a low-dimensional manifold, creating a mismatch between the inductive bias of existing methods and the structure of the data, often resulting in degraded performance. To address this mismatch, we introduce a geometric perspective. Specifically, we learn a pro
This paper offers a foundational improvement in anomaly detection, indicating that the field is maturing beyond initial assumptions and addressing specific data challenges.
Improved anomaly detection, especially for structural data, is critical for cybersecurity, industrial monitoring, and scientific discovery, impacting reliability and security across multiple domains.
The shift from density/boundary estimation to geometric projection operators provides a more suitable and potentially more accurate approach for detecting anomalies in intrinsically low-dimensional data structures.
