Table 1:
Parameter | Description |
---|---|
nParts | Number of parts of the partition |
fp | Multiplicative factor for oversampling the minority class. For instance with fp = 2 two novel examples are synthesized for each positive example of the original dataset, according to the SMOTE algorithm |
ratio | Ratio for the undersampling of the majority class. For instance, ratio = 2 sets the number of negative examples as twice the total number of original and oversampled positive examples |
k | Number of the nearest neighbours of the SMOTE algorithm |
nTrees | Number of trees included in each random forest |
mTry | Number of features to be randomly selected at each node of the decision trees included in the random forest |
