  • Built a pipeline coupling the CARLA simulator with VerifAI to synthesise adversarial examples, then used them to train models that are provably more robust.
  • Computed certified L2 robustness radii with Alpha-CROWN via AutoLiRPA, which sidestepped the VRAM and latency bottlenecks that made standard Branch-and-Bound infeasible at this scale.
  • Falsification-driven active learning expanded certified L2 robustness radii by 48% over five training cycles, showing markedly better sample efficiency than random sampling.
