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).
D. It is impossible to guarantee that dropping a column from $\mathcal S$ will not decrease the minimum distance.

Which of the following statements is correct?
A. When applying stochastic gradient descent on the objective function $f(\boldsymbol{w}):=\sum_{n=1}^{30}\left\|\boldsymbol{w}-\boldsymbol{x}_{n}\right\|^{2}$ where $\boldsymbol{x}_{n}$ are the datapoints, a stochastic gradient step is roughly $30 \times$ faster than a full gradient step.
B. In practice, it could be good to let your model first overfit your task, and then apply drop-out or other regularization techniques.
C. When applying stochastic gradient descent on the objective function $f(\boldsymbol{w}):=\sum_{n=1}^{30} n \cdot\|\boldsymbol{w}\|^{2}$, a stochastic gradient (for the $n$-th summand) is given by $2 n \cdot \boldsymbol{w}$.
D. The function $f(\boldsymbol{u} ; \boldsymbol{v}):=g\left(\boldsymbol{u} \boldsymbol{v}^{\top}\right)$ is convex over the set of pairs of vectors $(\boldsymbol{u} ; \boldsymbol{v}) \in \mathbb{R}^{2} \times \mathbb{R}^{2}$, when $g: \mathbb{R}^{2 \times 2} \rightarrow \mathbb{R}$ is defined as $g(\boldsymbol{X}):=X_{12}+X_{21}$.
