Consider optimizing a matrix factorization $\boldsymbol{W} \boldsymbol{Z}^{\top}$ in the matrix completion setting, for $\boldsymbol{W} \in \mathbb{R}^{D \times K}$ and $\boldsymbol{Z} \in \mathbb{R}{ }^{N \times K}$. We write $\Omega$ for the set of observed matrix entries. Which of the following statements are correct?
A. Given any $\Omega$, for $K:=\min \{N, D\}$, there is an exact solution to the problem.
B. In general, a step of $\mathrm{SGD}$ will change all entries of the $\mathbf{W}$ and $\mathbf{Z}$ matrices.
C. Adding a Frob-norm regularizer for $\boldsymbol{W}$ and $\boldsymbol{Z}$ to the matrix factorization objective function makes the objective convex.
D. A step of alternating least squares is more costly than an SGD step.
E. For complete observations $\Omega=[1 \ldots D] \times[1 \ldots N]$, the problem can be solved by the singular value decomposition.
F. The cost of an SGD step depends on the number of observed entries.

A colleague challenges you to create a $(n-1,k,d_{min})$ code $\mathcal C'$ from a $(n,k,d_{min})$ code $\mathcal C$ as follows: given a generator matrix $G$ that generates $\mathcal C$, drop one column from $G$. Then, generate the new code with this truncated $k imes (n-1)$ generator matrix. The catch is that your colleague only gives you a set $\mathcal S=\{\vec s_1,\vec s_2, \vec s_3\}$ of $3$ columns of $G$ that you are allowed to drop, where $\vec s_1$ is the all-zeros vector, $\vec s_2$ is the all-ones vector, and $\vec s_3$ is a canonical basis vector. From the length of the columns $s_i$ you can infer $k$. You do not know $n$, neither do you know anything about the $n-3$ columns of $G$ that are not in $\mathcal S$. However, your colleague tells you that $G$ is in systematic form, i.e., $G=[I ~~ P]$ for some unknown $P$, and that all of the elements in $\mathcal S$ are columns of $P$. Which of the following options in $\mathcal S$ would you choose as the column of $G$ to drop?
A. $\vec s_1$ (the all-zeros vector).
B. $\vec s_2$ (the all-ones vector)
C. $\vec s_3$ (one of the canonical basis vectors).
