Deep neural networks (DNNs) are the workhorses of deep learning, which constitutes the state of the art in numerous application domains.

veriFIRE: Verifying an Industrial, Learning-Based Wildfire Detection System

no code implementations6 Dec 2022 Guy Amir, Ziv Freund, Guy Katz, Elad Mandelbaum, Idan Refaeli

In this short paper, we present our ongoing work on the veriFIRE project -- a collaboration between industry and academia, aimed at using verification for increasing the reliability of a real-world, safety-critical system.

Verifying Learning-Based Robotic Navigation Systems

no code implementations26 May 2022 Guy Amir, Davide Corsi, Raz Yerushalmi, Luca Marzari, David Harel, Alessandro Farinelli, Guy Katz

Our work is the first to establish the usefulness of DNN verification in identifying and filtering out suboptimal DRL policies in real-world robots, and we believe that the methods presented here are applicable to a wide range of systems that incorporate deep-learning-based agents.
