WebChen et al./Mode Clustering 5 clusters. For example, whereas a hard-clustering method might assign a point x to cluster 2, a soft clustering might give x an assignment vector a(x) = (0:01;0:8;0:01;0:08;0:1), re ecting both the high con dence that xbelongs to cluster 2 the nontrivial possibility that it belongs to cluster 5.
