Results on HMEC-Mouse data. Heatmaps showing the w vectors for the decomposition of the mouse samples into the HMEC classes. The four heatmaps correspond to the four decomposition variants, U, P, S, and L, as indicated above each of the heatmaps. Each heatmap lists the 14 mouse samples along the x-axis, and the five HMEC classes along the y-axis. The heatmap reflects the w vectors that were obtained by decomposing each mouse sample separately. Each column contains one cross, indicating the largest absolute weight in that particular w vector, and thus the class assignment for that particular mouse sample. These solutions correspond to the case where the union of top 70 most differentiating genes for the separate one-versus-rest HMEC class comparisons are employed to represent the HMEC classes.
