Detectability of Subtle Anomalies in Dynamical Systems via Log-Likelihood Ratio
Alejandro Penacho Riveiros, Matthieu Barreau, Nicola Bastianello
Industrial control applications require detecting system anomalies as accurately and quickly as possible to enable prompt maintenance. In this context, it is common to consider sev…
Model-free Anomaly Detection for Dynamical Systems with Gaussian Processes
Alejandro Penacho Riveiros, Nicola Bastianello, Matthieu Barreau
In this paper we address the problem of detecting differences or anomalies in a dynamical system, based on historical data of nominal operations. This problem encompasses quality c…
Physics-Informed Detection of Friction Anomalies in Satellite Reaction Wheels
Alejandro Penacho Riveiros, Nicola Bastianello, Karl H. Johansson +1
As the number of satellites in orbit has increased exponentially in recent years, ensuring their correct functionality has started to require automated methods to decrease human wo…
Formal Verification of Local Robustness of a Classification Algorithm for a Spatial Use Case
Delphine Longuet, Amira Elouazzani, Alejandro Penacho Riveiros +1
Failures in satellite components are costly and challenging to address, often requiring significant human and material resources. Embedding a hybrid AI-based system for fault detec…
