Adversarial Attacks

Covers concrete attack types and limits: gradient-based minimal perturbations (DeepFool-style, L1/L2 norms) that flip a panda to a gibbon with imperceptible noise, white-box vs black-box and data poisoning that corrupts training labels, publicized Google Cloud Vision evasion and antivirus evasion examples, and real harms like medical image tampering (altered X‑rays/blood results). Shows defenses—adversarial training, input filtering, robust preprocessing—are costly, brittle and part of an ongoing attacker–defender arms race.
