WebSMOTE (Chawla et. al. 2002) is a well-known algorithm to fight this problem. The general idea of this method is to artificially generate new examples of the minority class using the nearest neighbors of these cases. Furthermore, the majority class examples are also under-sampled, leading to a more balanced dataset. Web17 Feb 2024 · The use of SMOTE in machine learning involves the following steps: Load and preprocess the imbalanced dataset, splitting it into training and testing sets.
