Abstract

Model checking aims to derive rigorous proofs for the correctness of systems and has traditionally relied on symbolic reasoning methods.
In this talk, I will argue that model checking can also be effectively addressed using machine learning too. I will present a realm of approaches for formal verification that leverage neural networks to represent correctness certificates of systems, known as "neural certificates." This approach trains certificates from synthetic executions of the system and then validates them using symbolic reasoning techniques. Building upon the observation that checking a correctness certificate is much simpler than finding one, and that neural networks are an appropriate representation for such certificates, this results in a machine learning approach to model checking that is entirely unsupervised, formally sound, and practically effective. I will demonstrate the principles and experimental results of this approach in safety assurance of software, probabilistic systems, and control.
