Fig. 2From: Meta-analysis of cell- specific transcriptomic data using fuzzy c-means clustering discovers versatile viral responsive genesOptimization of FCM parameters. a Average membership value (y-axis) per cluster with increasing fuzziness (x-axis), b Average number of genes per cluster (y-axis) for increasing fuzziness (x-axis) and four cluster association criteria, c 50 trials conducted with random initial assignment of the centroids found only 16% reproducible clusters, d Objective function values for FCM clustering with initial centroid assignment performed randomly and by Ward’s method (red line) under fuzziness 1.1, 1.2 and 1.3 respectively. Ward based initialization converged more rapidly and produced stable and robust clustering solutionBack to article page
