Classification of PDAC into 6 subtypes. a Unsupervised classification of PDAC using NMF. A peak cophenetic correlation was observed for k = 6 classes. b Consensus matrix for k = 6 is shown. c Silhouette information for k = 6 classes. d Patient distribution in the training dataset (n = 796). e Patient distribution in the merged validation dataset (n = 472)
