Detection of Dataset Shifts in Learning-Enabled Cyber-Physical Systems using Variational Autoencoder for Regression

no code implementations14 Apr 2021 Feiyang Cai, Ali I. Ozdagli, Xenofon Koutsoukos

Cyber-physical systems (CPSs) use learning-enabled components (LECs) extensively to cope with various complex tasks under high-uncertainty environments.

Detecting Adversarial Examples in Learning-Enabled Cyber-Physical Systems using Variational Autoencoder for Regression

no code implementations21 Mar 2020 Feiyang Cai, Jiani Li, Xenofon Koutsoukos

Learning-enabled components (LECs) are widely used in cyber-physical systems (CPS) since they can handle the uncertainty and variability of the environment and increase the level of autonomy.

Real-time Out-of-distribution Detection in Learning-Enabled Cyber-Physical Systems

no code implementations28 Jan 2020 Feiyang Cai, Xenofon Koutsoukos

The simulation results show very small number of false positives and detection delay while the execution time is comparable to the execution time of the original machine learning components.
