From: An AUC-based permutation variable importance measure for random forests
VIs computed only from OOB observations of the minority class (top), from OOB observations of the majority class (middle) and from all OOB observations (bottom). The first 15 predictors are associated with the response while the remaining predictors are noise predictors. VIs are shown for a total sample size of n = 500 and an imbalance level of 5%.
