SMOTE stands forSynthetic Minority Oversampling Techniquethat can be used to oversample the data and create equal number of majority and minority classes. It works on the principle of k-nearest neighbor algorithm in order to create synthetic data points. The data points are conv...
Synthetic Minority Oversampling Technique (SMOTE) – Creates synthetic data from the minority class by by selecting examples that are close in the feature space, drawing a line between the examples in the feature space and drawing a new sample at a point along that line. ...
and you’ve read how you should use oversampling to “fix” it. After some googling, you find SMOTE, an algorithm that uses the nearest neighbors to generate new samples in order to balance the minority class. Let’s apply this technique to a dataset called credit_g, from ...

Weighting is a technique for improving models. In this article, learn more about what weighting is, why you should (and shouldn’t) use it, and how to choose optimal weights to minimize business costs.
Oversampling with SMOTE (Synthetic Minority Over-sampling Technique) A combination of both random undersampling and oversampling using pipeline. Why accuracy is not good for imbalanced dataset? … in the framework of imbalanced data-sets,accuracy is no longer a proper measure, since it does not ...

In the top branch, we train the baseline model, while in the bottom branch we train the model on the bootstrapped training set using the SMOTE technique. This workflow is downloadable from Cohen’s Kappa for Evaluating Classification Models page on the KNIME Hub....
