Anomaly detection benchmarking needs rethinking, paper argues

A new position paper argues that current benchmarking methods for anomaly detection algorithms are inadequate and hinder progress. The paper highlights that simple algorithms often perform competitively with advanced deep learning models, and existing benchmarks do not reflect the diverse real-world applications of anomaly detection. To address this, the authors propose a new approach that groups applications into scenarios based on a common taxonomy, allowing for scenario-specific choices in preprocessing, metrics, and model selection to provide better guidance for practitioners.

    We Need to Rethink Benchmarking in Anomaly Detection

    arXiv:2507.15584v2 Announce Type: replace Abstract: Despite the continuous proposal of new anomaly detection algorithms and extensive benchmarking efforts, progress seems to stagnate, with only minor performance differences between established baselines and new algorithms. In thi…
