Pаrt (c): Nоw suppоse Alice wаnts tо use FGSM to crаft adversarial examples using her chosen model, which we denote by f. Recall that targeted FGSM starts from a benign input x0 and computes the adversarial example xadv with label y as xadv = clip[x0 - ε sign(∂L/∂x(f(x0), t))].Here ∂L/∂x denotes the gradient of the loss with respect to the parameters, t is the target class label (t≠y), and ε is the perturbation scale. Suppose valid examples have their features in [0,1]. Let x0 = (0.07, 0.93, 0.56), ε=0.1, and suppose that the gradient vector is (0.3, -0.02, -0.8). Calculate the adversarial example xadv.
