Solution
The evaluation metrics that are specific to clustering tasks are the Silhouette score and the adjusted Rand index.
-
Silhouette Score: This metric calculates the mean distance between a sample and all other points in the next nearest cluster. The silhouette score ranges from -1 to 1, where a high value indicates that the object is well matched to its own cluster and poorly matched to neighboring clusters. If most objects have a high value, then the clustering configuration is appropriate. If many points have a low or negative value, then the clustering configuration may have too many or too few clusters.
