WebMay 11, 2024 · The imbalanced-learn Python library provides implementations for both of these combinations directly. Let’s take a closer look at each in turn. Combination of SMOTE and Tomek Links Undersampling. SMOTE is an oversampling method that synthesizes new plausible examples in the minority class. WebMar 1, 2024 · SMOTE is an over-sampling technique focused on generating synthetic tabular data. The general idea of SMOTE is the generation of synthetic data between each sample of the minority class and its “ k ” nearest neighbors. That is, for each one of the samples of the minority class, its “ k ” nearest neighbors are located (by default k = 5 ...
