LBF distribution clusters and cluster histograms for 6208 S1 and T4-2 cells cultured for different numbers of days. (a) Twenty LBF distribution clusters automatically determined by probabilistic ensemble clustering of the results generated by Gaussian mixture model, fuzzy C-means, hierarchical clustering, K-means, and spectral clustering. The number of the clusters predefined for these baseline methods is 14. The clusters are ordered from the left to the right and the top to the bottom according to their peak locations. (b) From the left to right and the top to the bottom: cluster histograms of non-neoplastic S1 cells cultured in 3 days, 5 days, 10 days, and 12 days, and of malignant T4-2 cells cultured in 4 days, 5 days, 10 days, and 11 days.
