The following are multiple choice questions (with answers) about knowledge and skills in advanced master-level STEM courses.
Consider a binary classification problem with a linear classifier $f(\mathbf{x})$ given by $$ f(\mathbf{x})= \begin{cases}1, & \mathbf{w}^{\top} \mathbf{x} \geq 0 \\ -1, & \mathbf{w}^{\top} \mathbf{x}<0\end{cases} $$ where $\mathbf{x} \in \mathbb{R}^{3}$. 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 $\mathbf{x}=$ $(-1,3,2) ?$

Consider our standard least-squares problem $$ \operatorname{argmin}_{\mathbf{w}} \mathcal{L}(\mathbf{w})=\operatorname{argmin}_{\mathbf{w}} \frac{1}{2} \sum_{n=1}^{N}\left(y_{n}-\mathbf{x}_{n}^{\top} \mathbf{w}\right)^{2}+\frac{\lambda}{2} \sum_{d=1}^{D} w_{d}^{2} $$ Here, $\left\{\left(\mathbf{x}_{n} y_{n}\right)\right\}_{n=1}^{N}$ is the data. The $N$-length vector of outputs is denoted by $\mathbf{y}$. The $N \times D$ data matrix is called $\mathbf{X}$. It's rows contain the tuples $\mathbf{x}_{n}$. Finally, the parameter vector of length $D$ is called $\mathbf{w}$. (All just like we defined in the course). Mark any of the following formulas that represent an equivalent way of solving this problem.
A. $\operatorname{argmin}_{\boldsymbol{\alpha}} \frac{1}{2} \boldsymbol{\alpha}^{\top}\left(\mathbf{X X}^{\top}+\lambda \mathbf{I}_{N}\right) \boldsymbol{\alpha}-\boldsymbol{\alpha}^{\top} \mathbf{y}$
B. $\operatorname{argmin}_{\mathbf{w}} \sum_{n=1}^{N}\left[1-y_{n} \mathbf{x}_{n}^{\top} \mathbf{w}\right]_{+}+\frac{\lambda}{2}\|\mathbf{w}\|^{2}$. Recall: $[z]_{+}=\max \{0, z\}$
C. $\operatorname{argmin}_{\mathbf{w}}-\log p(\mathbf{y} \mid \mathbf{X}, \mathbf{w}) p(\mathbf{w})$, where $p(\mathbf{w})$ correspond to the density of a $D$-length vector of iid zero-mean Gaussians with variance $1 / \lambda$ and $p(\mathbf{y} \mid \mathbf{X}, \mathbf{w})$ corresponds to the density of a vector of length $N$ of independent Gaussians of mean $\mathbf{x}_{n}^{\top} \mathbf{w}$, variance 1 and observation $\mathbf{y}_{n}$ for component $n$.
D. $\square \operatorname{argmin}_{\mathbf{w}} \frac{1}{2} \sum_{n=1}^{N} \ln \left(1+e^{\mathbf{x}_{n}^{\top} \mathbf{w}}\right)-y_{n} \mathbf{x}_{n}^{\top} \mathbf{w}$

The following are multiple choice questions (with answers) about knowledge and skills in advanced master-level STEM courses.
Consider a movie recommendation system which minimizes the following objective
rac{1}{2} \sum_{(d,n)\in\Omega} [x_{dn} - (\mathbf{W} \mathbf{Z}^ op)_{dn}]^2 + rac{\lambda_w}{2}
orm{\mathbf{W}}_ ext{Frob}^2 + rac{\lambda_z}{2}
orm{\mathbf{Z}}_ ext{Frob}^2
where $\mathbf{W}\in \R^{D imes K}$ and $\mathbf{Z}\in \R^{N imes K}$.
Suppose movies are divided into genre A and genre B (i.e., $\mathbf{W}_A\in \R^{D_A imes K}, \mathbf{W}_B\in \R^{D_B imes K}, \mathbf{W}=[\mathbf{W}_A; \mathbf{W}_B]$, with $D_A\!+\!D_B=D$) and users are divided into group 1 and group 2 (i.e., $\mathbf{Z}_1\in \R^{N_1 imes K}, \mathbf{Z}_2\in \R^{N_2 imes K}, \mathbf{Z}=[\mathbf{Z}_1; \mathbf{Z}_2]$, with $N_1\!+\!N_2=N$). In addition, group 1 users only rate genre A movies while group 2 users only rate genre B movies. Then instead of training a large recommendation system with $(\mathbf{W}, \mathbf{Z})$, one may train two smaller recommendation systems with parameters $(\mathbf{W_A}, \mathbf{Z_1})$ and $(\mathbf{W_B}, \mathbf{Z_2})$ separately. If SGD is used to solve the minimization problems and all conditions remain the same (e.g., hyperparameters, sampling order, initialization, etc), then which of the following statements is true about the two training methods?
A. Feature vectors obtained in both cases remain the same.
B. Feature vectors obtained in both cases are different.
C. Feature vectors obtained in both cases can be either same or different, depending on the sparsity of rating matrix.
D. Feature vectors obtained in both cases can be either same or different, depending on if ratings in two groups and genres are evenly distributed.
