Impact of two-cluster overlap on clustering results for K-means algorithm and bipartite-graph model. a) Mean angular change of SSR(K) (bipartite-graph model) and within-cluster scatter (K-means) at K = 2. b) Mean misclassification rates of K-means and bipartite-graph model (see text) compared to theoretical prediction. All curves coincide. c) Mean squared-error loss of bipartite-graph model.
