Abstract	Imbalanced datasets pose significant challenges in machine learning, particularly in the automotive industry, where predicting rare events such as customer acquisition or retention is critical. Synthetic Minority Oversampling Technique (SMOTE) and TOMEK Link undersampling methods offer powerful solutions to balance these datasets and improve model performance. This paper explores these techniques in the context of customer acquisition models for a major luxury automotive brand, demonstrating how they enhance predictive accuracy and stability.
