Dynamic Simplex: Balancing Safety and Performance in Autonomous Cyber Physical Systems
To address these limitations, we propose a dynamic simplex strategy with an online controller switching logic that allows two-way switching.
ANTI-CARLA: An Adversarial Testing Framework for Autonomous Vehicles in CARLA
A key part of such tests is adversarial testing, in which the goal is to find scenarios that lead to failures of the given system.
Risk-Aware Scene Sampling for Dynamic Assurance of Autonomous Systems
Our samplers of RNS and GBO sampled a higher percentage of high-risk scenes of 83% and 92%, compared to 56%, 66% and 71% of the grid, random and Halton samplers, respectively.
Efficient Out-of-Distribution Detection Using Latent Space of $β$-VAE for Cyber-Physical Systems
In this paper, we study this problem as a multi-labeled time series OOD detection problem over images, where the OOD is defined both sequentially across short time windows (change points) as well as across the training data distribution.

Deep-RBF Networks for Anomaly Detection in Automotive Cyber-Physical Systems
In this paper, we show how the deep-RBF network can be used for detecting anomalies in CPS regression tasks such as continuous steering predictions.
ReSonAte: A Runtime Risk Assessment Framework for Autonomous Systems
To help with this process, we provide a scenario modeling procedure that can use the prior distributions of the scenes and threat conditions to generate the data required for estimating the conditional relationships.

Out-of-Distribution Detection in Multi-Label Datasets using Latent Space of $β$-VAE
We use the fact that compact latent space generated by an appropriately selected $\beta$-VAE will encode the information about these factors in a few latent variables, and that can be used for computationally inexpensive detection.
Dynamic-Weighted Simplex Strategy for Learning Enabled Cyber Physical Systems
This architecture integrates the system to be assured with a safe controller and provides a decision logic to switch between the decisions of these controllers.
