www.stat.cmu.eduThe sum of squares measures distance equally in all directions, so it wants the clusters to be round. This is not always very sensible (see Figure 2). 2.2 Single-link Clustering Single-linkclustering de nes the distance between two clusters as the minimum distance between their members: d(A;B) min ~x2A;~y2B k~x ~yk (4)
