Fig. 1From: Which data subset should be augmented for deep learning? a simulation study using urothelial cell carcinoma histopathology imagesOverall workflow of the study. Each color-coded pair of successive steps represents a different phase, namely, dataset building, dataset preprocessing, model building and testing, and statistical analysis. Note that five-fold cross validation was applied to model building and testing. UCC = urothelial cell carcinoma; CNNs = convolutional neural networksBack to article page
