From: Critical limitations of consensus clustering in class discovery
Consensus heatmaps show apparent clusters even for samples in unimodal distributions.
The top panels show Circle1 sample clusters with k-means partitioning for K = 2–5 (in a–d), displayed with PC1 (17.7%) on the x-axis and PC2 (15.1%) on the y-axis. The bottom panels show consensus heatmaps for K = 2–5 with 80% sample subsampling and k-means as the base method. The top panels in (e–h) show Square1 sample clusters with k-means partitioning for K = 2–5 displayed on PC1 (21.8%) and PC2 (19.1%). The bottom panels show consensus heatmaps for K = 2–5 with 80% sample subsampling and k-means as the base method.
