Recent approaches to leveraging deep learning for computing reachable sets of continuous-time dynamical systems have gained popularity over traditional level-set methods.
The introduction of an epsilon-approximate Hamilton-Jacobi Partial Differential Equation (HJ-PDE) establishes a relationship between training loss and accuracy of the true reachable set.
Satisfiability Modulo Theories (SMT) solvers are used to bound the residual error of the HJ-based loss function, allowing for formal certification of the approximation.
Certified Approximate Reachability (CARe) is the first approach to provide soundness guarantees on learned reachable sets of continuous dynamical systems.
