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.

Let $K_1$ be a uniformly distributed binary key length $n$. Let $K_2$ be the complement of $K_1$. Let $K_3$ be the reverse of $K_1$. Let $K_i||K_j$ denote the concatenation of the two keys. True or false: Encryption with the key $K_4 = ( K_1|| K_1 ) $, $P_{K_4}(M)$ provides perfect secrecy.
