In this case, class 1 has the most examples with 76, therefore, SMOTE will oversample all classes to have 76 examples. The complete example of oversampling the glass dataset with SMOTE is listed below.

If “auto”, this will be determined by the ratio … WitrynaClass to perform oversampling using K-Means SMOTE. K-Means SMOTE works in three steps: Cluster the entire input space using k-means. Distribute the number of samples to generate across clusters: Select clusters which have a high number of minority class samples. Assign more synthetic samples to clusters where minority class samples are …
