Scatterplot of the two highest membership values of all genes. Scatter plots of the two highest membership values of all genes for the optimal m in the dataset. The distribution of the highest two membership values is observed using the scatter plot of the first two highest memberships for each gene for the optimal m and three normalization methods. The x axis indicates the first highest membership, the y axis indicates the second highest membership, and the vertical line indicates the median value of the highest membership value. (a) Serum data (b) sporulation data (c) yeast data.
