Untargeted Adversarial Attacks
Adversarial attacks that just want your model to be confused and predict a wrong class are called Untargeted Adversarial Attacks.
- nicht zielgerichtet
Fast Gradient Sign Method(FGSM)
FGSM is a single step attack, ie.. the perturbation is added in a single step instead of adding it over a loop (Iterative attack).
Basic Iterative Method
Störung, anstatt in einem einzelnen Schritt in mehrere kleinen Schrittgrößen anwenden
Iterative Least-Likely Class Method
ein Bild erstellen, welches in der Vorhersage den niedrigsten Score trägt
Targeted Adversarial Attacks
Attacks which compel the model to predict a (wrong) desired output are called Targeted Adversarial attacks
- zielgerichtet
(Un-)Targeted Adversarial Attacks
kann beides...
Projected Gradient Descent (PGD)
Eine Störung finden die den Verlust eines Modells bei einer bestimmten Eingabe maximiert:

on computer vision
propose zeroth order optimization (ZOO)
- attacks to directly estimate the gradients of the targeted DNN
Black-Box Attacks using Adversarial Samples
- a technique that uses the victim model as an oracle to label a synthetic training set for the substitute, so the attacker need not even collect a training set to mount the attack
