On ARX modeling with the ASYM method for errors-in-variables problems

ARX models are often used in system identification. Using high-order ARX models one can well describe arbitrary output noise. Combining high-order ARX models and model reduction techniques, several two-step identification methods are formed, such as the asymptotic method (ASYM) (...

A Generic Framework for Multivariate Anomaly Detection and Root-Cause Analysis Using Slow and Fast Detection in Process Industries

The digitalization of process industries via the Industrial Internet of Things (IIoT) has introduced challenges like poor generalization, lack of interpretability, and complex multi-frequency sensor data. Most existing systems struggle to simultaneously detect anomalies and trace...
