EPCAM and lung cancer: (b) Central nervous system versus lung cancer cell lineage classifier. Results for a test set classification as either CNS or lung cancer primary cell lines using a random forest classifier. Lineages are classified using a classifier trained on the graph texture metrics for the subgraph of interacting epithelial-mesenchymal transition-related proteins VIM and EPCAM (Puram et al2017, Cook and Vanderhyden 2020).
