Additional file 1: Figure S1. ROC plots for predicting isocitrate dehydrogenase (IDH) mutation and chromosome 1p/19q codeletion simultaneously. We trained SVM, RF, and AB with feature selection within each fold (10-fold cross validation) to classify patients into one of three groups simultaneously. a. IDH wt. b. IDH mut-codel. c. IDH mut-non-codel.
