Fast Gradient Sign Method 

    attack-type : black box
    goals :       targeted
    time :        training
  • If you can gradient descend, you can also gradient ascent… it’s a double edged sword
  • In other words, if you know the direction to move the weights and biases which minimises loss, you also know the direction to go in order to maximise loss (just multiply by -1), which is inherently dangerous.
