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.

Consider two distributions $P_0,P_1$ with the same supports and a distinguisher $\mathcal{A}$ that makes $q$ queries. Tick the \textit{incorrect} assertion.
A. When $q=1$, $\mathsf{Adv}(\mathcal{A})\leq d(P_0,P_1)$ where $d$ is the statistical distance.
B. When $q>1$, $\mathsf{Adv}(\mathcal{A})\leq \frac{d(P_0,P_1)}{q}$ where $d$ is the statistical distance.
C. When $q=1$, the strategy ``return 1 $\Leftrightarrow \frac{P_0(x)}{P_1(x)}\leq 1$'' achieves the best advantage.
D. To achieve good advantage, we need to have $q\approx 1/C(P_0,P_1)$ where $C$ is the Chernoff information.
