Our task is to classify whether an animal is a dog (class 0) or a cat (class 1) based on the following features:
egin{itemize}
\item $x_1$: height
\item $x_2$: length of whiskers
\item $x_3$: thickness of fur
\end{itemize}
We perform standard normal scaling on the training features so that they have a mean of zero and standard deviation of 1. We have trained a Logistic Regression model to determine the probability that the animal is a cat, $p(1 | \mathbf{x,w})$.
Our classifier learns that cats have a lower height and longer whiskers than dogs, while the thickness of fur is not relevant to the classification outcome. Which of the following is true about the weights~$\wv$ learned by the classifier?
A. $w_1 < w_2 < w_3$
B. $w_1 < w_3 < w_2$

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.
