why is euclidean distance normalized in hierarchical clustering why normalize hierarchical clustering why would you normally normalize hierarchical clustering how do you normalize distance measures in hierarchical clustering why is clustering required to be standardized why normalize for distance why is hierarchical clustering necessary why should euclidean distance measures be normalized for clustering why do we normalize euclidean distance measures why does data need to be normalized why is data normalized? why must euclidean distance be normalized why is hierarchical clustering important why does clustering require data standardization why should a distance measure be normalized why is it necessary to normalize a distance measure why would you normalize the euclidean distance why use euclidean distances in hierarchical clustering why should distance be normalized in clustering? why is it useful to normalize hierarchical clustering?
