To address these limitations, we propose a dynamic simplex strategy with an online controller switching logic that allows two-way switching.

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.

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.

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.

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.

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.
