Title: Neuro-symbolic Liveness Verification

Abstract: Liveness verification answers the question of whether a system always responds with desirable behavior or, dually, never gets stuck without responding at all. For dynamical systems, this relates to the stability question; for computer programs, it relates to the halting problem. I will talk about a novel method for constructing liveness proofs by learning witnesses (Lyapunov and ranking functions) from data using neural networks combined with symbolic reasoning. I will talk about how we apply this neuro-symbolic approach to the stability analysis of dynamical systems, to the termination analysis of Java programs, and to the almost-sure termination analysis of probabilistic programs.
