Suppose that the weights of the linear model are equal to $\mathbf{w}=(4,0,-3)$. For the next two questions, we would like to find a minimum-norm adversarial example. Specifically, we are interested in solving the following optimization problem, for a given $\mathbf{x}$ : $$ \min _{\boldsymbol{\delta} \in \mathbb{R}^{3}}\|\boldsymbol{\delta}\|_{2} \quad \text { subject to } \quad \mathbf{w}^{\top}(\mathbf{x}+\boldsymbol{\delta})=0 $$ This leads to the point $\mathbf{x}+\boldsymbol{\delta}$ that lies exactly at the decision boundary and the perturbation $\boldsymbol{\delta}$ is the smallest in terms of the $\ell_{2}$-norm. What is the optimum $\delta^{\star}$ that minimizes the objective in Eq. (OP) for the point $\mathbf{x}=$ $(-1,3,2) ?$
