🛡️Adversarial Robustness

NEW

The resilience of a model against adversarial perturbations that aim to deceive its predictions.

DESCRIPTION

Adversarial robustness concerns the ability of AI models to withstand intentionally crafted inputs designed to cause misclassification or failure. It is critical for safety-critical and high-stakes applications. Common evaluation uses attacks like FGSM and PGD, and defenses include adversarial training, certified methods, and robust optimization. Robustness often trades off with clean-data accuracy. Operational robustness requires monitoring, retraining, and red-teaming in production.

ALTERNATIVE DEFINITIONS

NIST

Robustness is the ability of a machine learning component to maintain acceptable performance when subject to perturbations or attacks.

Defines robustness within a formal taxonomy for adversarial machine learning.
