Your aim is to evaluate a Tweet analysis system, the
purpose of which is to detect whether a tweet is offensive. For each Tweet processed, such a system outputs one of the following classes: "hateful",
"offensive" and "neutral".To perform your evaluation, you
collect a large set of Tweets and have it annotated by two human
annotators. This corpus contains 1% of "hateful" and 4% of
"offensive" Tweets.What metrics do you think are appropriate to evaluate such a system?(penalty for wrong ticks)
A. Cohen's kappa
B. accuracy
C. precision
D. recall
E. standard deviation

Consider a binary classification problem with classifier $f(\mathbf{x})$ given by $$ f(\mathbf{x})= \begin{cases}1, & g(\mathbf{x}) \geq 0 \\ -1, & g(\mathbf{x})<0\end{cases} $$ and $\mathbf{x} \in \mathbb{R}^{6}$. Consider a specific pair $(\mathbf{x}, y=1)$ and assume that $g(\mathbf{x})=8$. In particular this means that this point is classified correctly by $f$. Assume further that we have computed the gradient of $g$ at $\mathbf{x}$ to be $\nabla_{\mathbf{x}} g(\mathbf{x})=(+1,-2,+3,-4,+5,-6)$. You are allowed to make one step in order to (hopefully) find an adversarial example. In the following four questions, assume $\epsilon=1$. Which offset $\delta$ with $\|\delta\|_{1} \leq 1$ yields the smallest value for $g(\mathbf{x}+\delta)$, assuming that $g$ is (locally) linear?
A. $(0,0,0,0,0,1)$
B. $(+1,-1,+1,-1,+1,-1)$
C. $(+1,-2,+3,-4,+5,-6)$
D. $(+1,+1,+1,+1,+1,+1)$
E. $(-1,+2,-3,+4,-5,+6)$
F. $(0,0,0,0,0,1)$
G. $(-1,+1,-1,+1,-1,+1)$
H. $(-1,-1,-1,-1,-1,-1)$
