Results on the MCF7-Human breast cancer data. Output from the lasso-based decomposition variant (L), on 509 human breast cancer samples. The red and white heatmap indicates the w vectors for all samples (n = 70). Samples with the same single non-zero weight are grouped together. For the small group of samples on the left, all weights are zero, whereas for the samples on the right more than one element of w is non-zero. The ER status, whether a metastasis event occurred, and the subtyping according to Hu et al. are indicated by the top three colored rows above the heatmap. The groups formed based on which weights are non-zero are indicated in the fourth row (i.e. derived from this heatmap).
