Generalized Outer Bounds on the Finite Geometric Sum of Ellipsoids
Navid Hashemi, Justin Ruths
General results on convex bodies are reviewed and used to derive an exact closed-form parametric formula for the boundary of the geometric (Minkowski) sum of ellipsoids in -…
Finite sample guarantees for quantile estimation: An application to detector threshold tuning
David Umsonst, Justin Ruths, Henrik Sandberg
In threshold-based anomaly detection, we want to tune the threshold of a detector to achieve an acceptable false alarm rate. However, tuning the threshold is often a non-trivial ta…
Performance Bounds for Neural Network Estimators: Applications in Fault Detection
Navid Hashemi, Mahyar Fazlyab, Justin Ruths
We exploit recent results in quantifying the robustness of neural networks to input variations to construct and tune a model-based anomaly detector, where the data-driven estimator…
Anomaly Detection Under Multiplicative Noise Model Uncertainty
Venkatraman Renganathan, Benjamin J. Gravell, Justin Ruths +1
State estimators are crucial components of anomaly detectors that are used to monitor cyber-physical systems. Many frequently-used state estimators are susceptible to model risk as…
