In-Depth Information
not typical mammals, but they are an important category if we would like to explore
different kinds of mammals
To show the difference between typicality analysis and clustering analysis, we
apply the
k
-medoids clustering algorithm [83] to the Zoo data set. We first com-
pute the 10 clusters of the Zoo data set. The median animals of the clusters are
{
Starfish, Boar, Lark, Tuatara, Dolphin, Flea, Bass, Mink, Scorpion, Hare
}
. The
.
group typicality score of the set of median animals is 0
182. At the same time, the
group typicality score of the answer set of the top-10 most representatively typical
animals shown in Table 4.3 is 0
216. Therefore, the set of animals found by the
clustering analysis is only 84% as representative as the set of animals found by the
top-
k
representative typicality queries.
