Compare the following two measures of the extent to which an object belongs to a cluster: (1) distance of an object from the centroid of its closest cluster and (2) the silhouette coefficient described in Section 8.5.2.

What will be an ideal response?


The first measure is somewhat limited since it disregards that fact that the
object may also be close to another cluster. The silhouette coefficient takes
into account both the distance of an object to its cluster and its distance
to other clusters. Thus, it can be more informative about how strongly an
object belongs to the cluster to which it was assigned.
