http://www.otlet-institute.org/wikics/Clustering_Problems.html WebbInertia can be recognized as a measure of how internally coherent clusters are. It suffers from various drawbacks: Inertia makes the assumption that clusters are convex and isotropic, which is not always the case. It responds poorly to elongated clusters, or manifolds with irregular shapes.
