Adversarial Extra

Adversarial

Adversarial example in some norm

在之前的ZOO可以看到我們創造的是$norm_2$的adversarial example
在JSMA創造的是$norm_\infty$
在EDA創造的是$norm_1$的例子,

Adversarial examples in more type

  • The use in CNN+RNN :

  • The use in speech recognition

  • The use in NLP with Sentiment Analysis,Fake-News Detection, Spam Filtering.

The improve of the ZOO -> AUTOZOO

  • (Auto encoder based Z eroth Order Optimization Method for Attacking Black box Neural Networks)
    主要做的有兩點:
  1. 使用了更新的gradient算法:
    The Old one

    The New one : $b \in (1, dimensions)$

    The Sucessful rate in iterations

  2. Use the dimension reduction:
    Here is the two method
    Left : Autoencoder
    Right: Biliner

STRUCTURED ADVERSARIAL ATTACK

ADMM used to solve the subproblem

‘ostrich’ is the original label, and ‘unicycle’ is the misclassified label.

將圖片分成一些區塊,並且將那些區塊做loss處理,並且用ADMM將方程式做處理,處理過後的方程式就不列上了,有點長
