Cluster Stability results on simulated datasets for k = 2 to k = 10. Stability scores for various values of k (2 to 10) are computed on all the 8 simulated datasets. For each dataset, we generate an output table of scores (explained in Algorithms section). We merge all the 8 output tables produced into one table with each cell computed as average of corresponding cells in 8 tables. Finally scores are plotted for all k values with respect to sample size. For cleaner visualization purposes, we do not show stability curves for all k values in figure 5c and figure 5d. a Scores plotted for CLARA for each k (2–10). b Scores plotted for K-means for each k (2–10). c Scores plotted for Fuzzy Cmeans for each k (2–10). d Scores plotted for SOM for each k (2–10).
