For each dataset, upside line of figure indicates the original clustering and the downside line indicates the noisy data clustering, and first and second columns are the results of FCM clustering and others two are the results of PAM clustering. The axis indicates the number of clusters, and axis indicates the values of data points (a) Serum data (b) sporulation data
