K-means Clustering via Principal Component Analysis?

WebCentroid Method: In centroid method, the distance between two clusters is the distance between the two mean vectors of the clusters. At each stage of the process we combine the two clusters that have the smallest centroid distance. Ward’s Method: This method does not directly define a measure of distance between two points or clusters. It is ... Webprototypes, the centroids of clusters, to characterize the data. They are determined by minimizing the sum of squared errors, JK = XK k=1 X i∈Ck (xi −mk)2 where (Px1,···,xn) = X is the data matrix and mk = i∈Ck xi/nk is the centroid of cluster Ck and nk is the number of points in Ck.
