WebPrinciple of the k-means method. k-means clustering is an iterative method which, wherever it starts from, converges on a solution. The solution obtained is not necessarily the same for all starting points. For this reason, the calculations are generally repeated several times in order to choose the optimal solution for the selected criterion. Web2) Hierarchical cluster is well suited for binary data because it allows to select from a great many distance functions invented for binary data and theoretically more sound for them than simply Euclidean distance.
