We consider a classification problem on linearly separable data. Our dataset had an outlier---a point that is very far from the other datapoints in distance (and also far from margins in SVM but still correctly classified by the SVM classifier).
We trained the SVM, logistic regression and 1-nearest-neighbour models on this dataset.
We tested trained models on a test set that comes from the same distribution as training set, but doesn't have any outlier points.
For any vector $ v \in \R^D$ let $\| v\|_2 := \sqrt{v_1^2 + \dots + v_D^2}$ denote the Euclidean norm. The hard-margin SVM problem for linearly separable points in $\R^D$ is to minimize the Euclidean norm $\| \wv \|_2$ under some constraints.
What are the additional constraints for this optimization problem?
A. $y_n \ww^ op x_n \geq 1 ~ orall n \in \{1,\cdots,N\}$
B. $\ww^ op x_n \geq 1 ~ orall n \in\{1,\cdots,N\}$

Let $\mathbb F$ be a field of cardinality $q$ and let $0<k<n\leq q$ be unspecified integers. As seen in the lecture, we generate a $(n,k,d_{min})$ Reed-Solomon code with the following mapping: $$\mathbb F^k
ightarrow \mathbb F^n ~~,~~ \vec u \mapsto \vec c =(P_{\vec u}(a_1),P_{\vec u}(a_2),\ldots,P_{\vec u}(a_n))$$ for $a_i \in \mathbb F$ all distinct and $P$ a polynomial of degree $k-1$ with coefficient vector $\vec u\in\mathbb F^k$. Now, we construct a $(n,k',d'_{min})$ code $\mathcal C'$ similarly to the above one by assigning $a_1\leftarrow a_2$ while leaving $n,P$ and $a_2,\ldots,a_n$ unchanged. As before, the code is generated by evaluating $P_{\vec u}(a_2,a_2,a_3,\dots,a_n)$ over all possible coefficients vectors $\vec u \in \mathbb F^k$. This is by definition not an RS code, however it is still a well-defined linear block code. True or false: We know for certain that $d'_{min}=d_{min}-1$.

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 $g(\boldsymbol{X}):=X_{12}+X_{21}$.
