PDM results for several benchmark data sets. Points are placed in the grid according to cluster assignment from layers 1 and 2 (in (a) and (b) no second layer is present). In (a) and (b) it can be seen that the PDM identifies three clusters, and that the division of the ALL samples in (a) corresponds to a subtype difference (ALL-B, ALL-T) shown in (b). In (c) and (d), it can be seen that the partitioning of samples in the first layer is refined in the second PDM layer.
