Figure 1.
Individual study clustering and MetaSparseKmeans result for 3 breast cancer datasets. Rows represent genes and columns represent samples. Red and green color represent higher and lower expression. In each study, the patients are divided into 5 clusters, represented by 5 unique colors in the color bar above the heatmaps. 1(a)-1(c): Sparse K-means result from three studies separately. 1(d)-1(f): MetaSparseKmeans result.
