4 points
In a dataset with ten points {A, B, C, D, E, F, G, H, I, J}, A and B are labeled outliers.
Five outlier detection methods, $m_1$,..., $m_5$, deliver the following rankings (from left-to-right: top-rank to bottom-rank):
method
ranking
$m_1$
C,D,A,E,F,B,G,H,I,J
$m_2$
C,A,D,E,J,G,B,H,I,F
$m_3$
D,I,A,E,F,G,B,H,C,J
$m_4$
E,J,I,A,B,F,G,H,C,D
$m_5$
F,A,E,J,H,D,C,B,I,G
Based on ROC AUC as evaluation measure, which of the following statements are correct?
$m_1$ and $m_2$ perform equally well.
$m_1$ is better than $m_3$.
$m_2$ is better than $m_3$.
$m_3$ is better than $m_4$.
$m_4$ is better than $m_5$.
$m_5$ is better than $m_1$.
$m_5$ is better than $m_2$.
$m_5$ is better than $m_4$.
true
false
