Two is Better Than One: Digital Siblings to Improve Autonomous Driving Testing

1 code implementation14 May 2023 Matteo Biagiola, Andrea Stocco, Vincenzo Riccio, Paolo Tonella

Our empirical evaluation shows that the ensemble failure predictor by the digital siblings is superior to each individual simulator at predicting the failures of the digital twin.

DeepMetis: Augmenting a Deep Learning Test Set to Increase its Mutation Score

1 code implementation15 Sep 2021 Vincenzo Riccio, Nargiz Humbatova, Gunel Jahangirova, Paolo Tonella

The adequacy of the test data used to test such systems can be assessed by their ability to expose artificially injected faults (mutations) that simulate real DL faults.

DeepHyperion: Exploring the Feature Space of Deep Learning-Based Systems through Illumination Search

1 code implementation5 Jul 2021 Tahereh Zohdinasab, Vincenzo Riccio, Alessio Gambi, Paolo Tonella

Deep Learning (DL) has been successfully applied to a wide range of application domains, including safety-critical ones.

Model-based Exploration of the Frontier of Behaviours for Deep Learning System Testing

1 code implementation6 Jul 2020 Vincenzo Riccio, Paolo Tonella

If the frontier of misbehaviours is outside the validity domain of the system, the quality check is passed.
