Figure 1From: Tumor classification and marker gene prediction by feature selection and fuzzy c-means clustering using microarray dataStress as a function of SOM reference vectors in model one. a) Leukemia data set. b) Colon data set. c) Brain tumor data set. d) NCI60 cancer cell line data set. In each plot, the optimal number of SOM reference vectors was marked by red vertical line and the number of SOM reference vectors was indicated by red text.Back to article page
