Recall that the hard-margin SVM problem corresponds to:
$$ \underset{\substack{\ww \in \R^d, \ orall i:\ y_i \ww^ op \xx_i \geq 1}}{\min} \Vert \ww \Vert_2.$$
Now consider the $2$-dimensional classification dataset corresponding to the $3$ following datapoints: $\xx_1 = (-1, 2)$, $\xx_2 = (1, 2)$, $\xx_3 = (0, -2)$ and $y_1 = y_2 = 1$, $y_3 = -1$.
Which of the following statements is extbf{true}:
A. Our dataset is not linearly separable and hence it does not make sense to consider the hard-margin problem.
B. There exists a unique $\ww^\star$ which linearly separates our dataset.
C. The unique vector which solves the hard-margin problem for our dataset is $\ww^\star = (0, 1)$.
D. None of the other statements are true.
