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.

B. $rgmax_{\|\deltav\|_2 \leq arepsilon} \log_2(1 + \exp(-y \wv^ op (\xv + \deltav))) = rgmin_{\|\deltav\|_2 \leq arepsilon} y \wv^ op (\xv + \deltav )$
C. $rgmax_{\|\deltav\|_2 \leq arepsilon} \log_2(1 + \exp(-y \wv^ op (\xv + \deltav))) = rgmax_{\|\deltav\|_2 \leq arepsilon} 1 - anh(y \wv^ op (\xv + \deltav))$ \ where $ anh(z) = rac{e^z - e^{-z}}{e^z + e^{-z}}$
D. $rgmax_{\|\deltav\|_2 \leq arepsilon} \log_2(1 + \exp(-y \wv^ op (\xv + \deltav))) = rgmax_{\|\deltav\|_2 \leq arepsilon} \mathbf{1}_{y \wv^ op (\xv + \deltav) \leq 0}$

The following are multiple choice questions (with answers) about knowledge and skills in advanced master-level STEM courses.
Consider a learning algorithm that has the property that it depends only very weakly on the input data. E.g., this could be SGD where we choose a very small step size and only run for very few iterations. To go to the extreme, you can imagine a learning algorithm that always outputs the same model irrespective of the training set. Presumably such a learning algorithm will not give us good results. Why is that?
A. (a) Such a learning algorithm typically has a much larger generalization error than training error.
B. (b) Such a learning algorithm typically has a large bias.
C. (c) Such a learning algorithm is prone to overfitting.
