Adversarial Training
Adversarial training is a method where the model is trained on both the original and adversarial examples, aiming to make the model more robust to adversarial attacks.
Feature Squeezing
Feature squeezing reduces the number of bits used to represent the input features, which can remove certain adversarial perturbations.
Gradient Masking
Gradient masking modifies the gradients during training to make them less informative for adversarial attackers.
Input Transformation
Input transformation applies a transformation to the input data before feeding it to the model, aiming to remove adversarial perturbations.
Defensive Distillation
Defensive distillation trains a student model to mimic the predictions of a teacher model, which is often a more robust model.
Randomized Smoothing
Randomized smoothing adds random noise to the input data to make the model more robust to adversarial attacks.
Feature Denoising
Feature denoising applies denoising operations to the input data to remove adversarial perturbations.
Thermometer Encoding
Thermometer encoding discretizes the input features into bins, making it harder for adversarial perturbations to affect the model.
Adversarial Logit Pairing (ALP)
Adversarial logit pairing encourages the logits of adversarial examples to be similar to those of clean examples.
Spatial Smoothing
Spatial smoothing applies a smoothing filter to the input data to remove adversarial perturbations.
