Question

1. Which is best to use when selecting a clustering procedure: hierarchical or nonhierarchical clustering?

Answer 1

Answer :

Best clustering technique to use hierarchical non-hierarchical clustering :-

like k-means

grouping which is hugely utilized in AI.

calculations which handles huge information well like genuine information.

A various leveled grouping technique delivers a characterization in which little bunches of fundamentally the same as particles are settled inside bigger bunches of less firmly related atoms.

A non-various leveled strategy produces a characterization by apportioning a data set, giving a lot of (for the most part) non-covering bunches having no progressive connections between them. An efficient assessment of every single imaginable parcel is very infeasible, and a wide range of heuristics have along these lines been depicted to permit the distinguishing proof of good, however potentially imperfect, segments.
