WebThe figure below illustrates the major difference of the different over-sampling methods. 2.1.3. Ill-posed examples#. While the RandomOverSampler is over-sampling by duplicating some of the original samples of the minority class, SMOTE and ADASYN generate new samples in by interpolation. However, the samples used to interpolate/generate new … Web22 Oct 2024 · What is SMOTE? SMOTE is an oversampling algorithm that relies on the concept of nearest neighbors to create its synthetic data. Proposed back in 2002 by …
