WebThe attack backpropagates the gradient back to the input data to calculate ∇ x J ( θ, x y). Then, it adjusts the input data by a small step ( ϵ or 0.007 in the picture) in the direction (i.e. s i g n ( ∇ x J ( θ, x y))) that will maximize the loss. The resulting perturbed image, x ′, is then misclassified by the target network as a ...
