A Survey of Algorithms for Black-Box Safety Validation [article]

Anthony Corso, Robert J. Moss, Mark Koren, Ritchie Lee, Mykel J. Kochenderfer
2020 arXiv   pre-print
Autonomous and semi-autonomous systems for safety-critical applications require rigorous testing before deployment.  ...  Safety validation tasks include finding disturbances to the system that cause it to fail (falsification), finding the most-likely failure, and estimating the probability that the system fails.  ...  Zhao et al. (2003) applied a genetic algorithm to generate test cases for embedded control systems.  ...

Requirements-driven Test Generation for Autonomous Vehicles with Machine Learning Components [article]

Cumhur Erkan Tuncali, Georgios Fainekos, Danil Prokhorov, Hisahiro Ito, James Kapinski
2019 arXiv   pre-print
We present STL requirements for an autonomous vehicle system, which capture both component-level and system-level behaviors.  ...  One of the key features of our tool is the support for machine learning (ML) components in the system design, such as deep neural networks.  ...  Here, we apply that approach on model M 1 for 3 different requirements, R1, R2 and R4. In model M 1 , we focus on the camera sensor and DNN-based object detection and classification algorithm.  ...

Robustness in Cyber-Physical Systems (Dagstuhl Seminar 16362)

Martin Fränzle, James Kapinski, Pavithra Prabhakhar, Marc Herbstritt
2017 Dagstuhl Reports  
This seminar brought together researchers from both academia and industry working in hybrid control systems, mechatronics, formal methods, and real-time embedded systems.  ...  Electronically controlled systems have become pervasive in modern society and are increasingly being used to control safety-critical applications, such as medical devices and transportation systems.  ...  Even though such notions of robustness may be useful for system design, they are not necessarily useful for the automatic test generation and falsification problems for dynamic safety.  ...
