The following are multiple choice questions (with answers) about knowledge and skills in advanced master-level STEM courses.
Consider a binary classification problem with classifier $f(\mathbf{x})$ given by $$ f(\mathbf{x})= \begin{cases}1, & g(\mathbf{x}) \geq 0 \\ -1, & g(\mathbf{x})<0\end{cases} $$ and $\mathbf{x} \in \mathbb{R}^{6}$. Consider a specific pair $(\mathbf{x}, y=1)$ and assume that $g(\mathbf{x})=8$. In particular this means that this point is classified correctly by $f$. Assume further that we have computed the gradient of $g$ at $\mathbf{x}$ to be $\nabla_{\mathbf{x}} g(\mathbf{x})=(+1,-2,+3,-4,+5,-6)$. You are allowed to make one step in order to (hopefully) find an adversarial example. In the following four questions, assume $\epsilon=1$. Which offset $\delta$ with $\|\delta\|_{1} \leq 1$ yields the smallest value for $g(\mathbf{x}+\delta)$, assuming that $g$ is (locally) linear?
A. $(0,0,0,0,0,1)$
B. $(+1,-1,+1,-1,+1,-1)$
C. $(+1,-2,+3,-4,+5,-6)$
D. $(+1,+1,+1,+1,+1,+1)$
E. $(-1,+2,-3,+4,-5,+6)$
F. $(0,0,0,0,0,1)$
G. $(-1,+1,-1,+1,-1,+1)$
