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. $\ww^ op x_n \geq 1 ~ orall n \in\{1,\cdots,N\}$

Consider the logistic regression loss $L: \R^d \to \R$ for a binary classification task with data $\left( xv_i, y_i\right) \in \R^d \times \{0, 1\}$ for $i \in \left\{ 1, \ldots N\right\}$:
\begin{equation*}
L(wv) = \frac{1}{N} \sum_{i = 1}^N \bigg(\log\left(1 + e^{xv_i^\top wv} \right) - y_i xv_i^\top wv \bigg).
\end{equation*}
Which of the following is a gradient of the loss $L$?

You are doing your ML project. It is a regression task under a square loss. Your neighbor uses linear regression and least squares. You are smarter. You are using a neural net with 10 layers and activations functions $f(x)=3 x$. You have a powerful laptop but not a supercomputer. You are betting your neighbor a beer at Satellite who will have a substantially better scores. However, at the end it will essentially be a tie, so we decide to have two beers and both pay. What is the reason for the outcome of this bet?
A. Because we use exactly the same scheme.
B. Because it is almost impossible to train a network with 10 layers without a supercomputer.
C. Because I should have used more layers.
D. Because I should have used only one layer.
