Classification performances of the iDRW method and four pathway-based methods with varying values of k for breast cancer (a) and neuroblastoma data (b). Classification performances with top-k pathway features are shown for each model with varying k = 5, 10, …, 45, 50. Performance is measured using precision, recall and F-1 score after 50 repeats of five-fold cross-validation in breast cancer data (a) and leave-one-out cross-validation in neuroblastoma data (b)
