Statistical Process Control Outperforms SOTA on TSB-AD Anomaly Detection Benchmark
August 29, 2026
Testing on the TSB-AD-M benchmark reveals that simple Statistical Process Control (SPC) achieves perfect results, surpassing modern state-of-the-art time series anomaly detection methods. This suggests current benchmark datasets may lack the complexity required to validate advanced machine learning models.
