Assume we have $N$ training samples $(\xx_1, y_1), \dots, (\xx_N, y_N)$ where for each sample $i \in \{1, \dots, N\}$ we have that $\xx_i \in \R^d$ and $y_i \in \{-1, 1\}$. We want to classify the dataset using the exponential loss $L(\ww) = rac{1}{N} \sum_{i=1}^N \exp (-y_i \xx_i^ op \ww )$ for $\ww \in \R^d$.
Which of the following statements is extbf{true}:
A. This corresponds to doing logistic regression as seen in class.
B. The loss function $L$ is non-convex in $\ww$.
C. If I find a vector $\ww^\star$ such that $L(\ww^\star) < 1 / N$, then $\ww^*$ linearly separates my dataset.
D. There exists a vector $\ww^\star$ such that $L(\ww^\star) = 0$.

A multiset is an unordered collection where elements can appear multiple times. We will represent a multiset of Char elements as a function from Char to Int: the function returns 0 for any Char argument that is not in the multiset, and the (positive) number of times it appears otherwise: type Multiset = Char => Int The filter operation on a multiset m returns the subset of m for which p holds. What should replace ??? so that the filter function is correct? def filter(m: Multiset, p: Char => Boolean): Multiset = ???
