SCUT                    SMOTE and cluster-based undersampling
                        technique.
bullseye                An imbalanced dataset with a minor class
                        centered around the origin with a majority
                        class surrounding the center.
imbalance               An imbalanced dataset with randomly placed
                        normal distributions around the origin. The nth
                        class has n * 10 observations.
oversample_smote        Oversample a dataset by SMOTE.
resample_random         Randomly resample a dataset.
sample_classes          Stratified index sample of different values in
                        a vector.
undersample_hclust      Undersample a dataset by hierarchical
                        clustering.
undersample_kmeans      Undersample a dataset by kmeans clustering.
undersample_mclust      Undersample a dataset by
                        expectation-maximization clustering
undersample_mindist     Undersample a dataset by iteratively removing
                        the observation with the lowest total distance
                        to its neighbors of the same class.
undersample_tomek       Undersample a dataset by removing Tomek links.
validate_dataset        Validate a dataset for resampling.
wine                    Type and chemical analysis of three different
                        kinds of wine.
