Scaling #DNN-Verification Tools with Efficient Bound Propagation and Parallel Computing

no code implementations10 Dec 2023 Luca Marzari, Gabriele Roncolato, Alessandro Farinelli

Deep Neural Networks (DNNs) are powerful tools that have shown extraordinary results in many scenarios, ranging from pattern recognition to complex robotic problems.

Enumerating Safe Regions in Deep Neural Networks with Provable Probabilistic Guarantees

no code implementations18 Aug 2023 Luca Marzari, Davide Corsi, Enrico Marchesini, Alessandro Farinelli, Ferdinando Cicalese

Identifying safe areas is a key point to guarantee trust for systems that are based on Deep Neural Networks (DNNs).

Safe Deep Reinforcement Learning by Verifying Task-Level Properties

no code implementations20 Feb 2023 Enrico Marchesini, Luca Marzari, Alessandro Farinelli, Christopher Amato

In this paper, we investigate an alternative approach that uses domain knowledge to quantify the risk in the proximity of such states by defining a violation metric.

Online Safety Property Collection and Refinement for Safe Deep Reinforcement Learning in Mapless Navigation

no code implementations13 Feb 2023 Luca Marzari, Enrico Marchesini, Alessandro Farinelli

Our evaluation compares the benefits of computing the number of violations using standard hard-coded properties and the ones generated with CROP.

The #DNN-Verification Problem: Counting Unsafe Inputs for Deep Neural Networks

no code implementations17 Jan 2023 Luca Marzari, Davide Corsi, Ferdinando Cicalese, Alessandro Farinelli

Due to the #P-completeness of the problem, we also propose a randomized, approximate method that provides a provable probabilistic bound of the correct count while significantly reducing computational requirements.

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.

Curriculum Learning for Safe Mapless Navigation

1 code implementation23 Dec 2021 Luca Marzari, Davide Corsi, Enrico Marchesini, Alessandro Farinelli

To this end, we present a CL approach that leverages Transfer of Learning (ToL) and fine-tuning in a Unity-based simulation with the Robotnik Kairos as a robotic agent.
