Web1 Answer Sorted by: 0 The default distance used in scipy.cluster.hierarchy.linkage is the euclidean distance, defined as d (x,y) = \sqrt (\sum (x_i-y_i)) (you can check it here ). I think the reason why you got confused is because you were taking the average (and computing the root mean squared error). So in your case d (A,B) = \sqrt (3) = 1.73 Web14 de fev. de 2016 · One of the biggest issue with cluster analysis is that we may happen to have to derive different conclusion when base on different clustering methods used (including different linkage methods in hierarchical clustering)..
