Dynamic curvature estimation (query-efficient decision-boundary curvature)

Techniqueadvanced

Estimates local decision-boundary curvature during a black-box adversarial attack's own query trajectory, tracking a 'curvature dynamic trajectory' as the attack converges, rather than a one-shot Monte Carlo volume estimate.

Used in (1 observation)

Standard classifiers have higher decision-boundary curvature than robust onesmeasured
