What do you do if your Machine Learning dataset is imbalanced?
Imbalanced datasets are a common challenge in Machine Learning, especially when dealing with classification problems. They occur when one class has significantly more samples than another, which can lead to biased models that favor the majority class and ignore the minority class. In this article, you will learn some strategies to deal with imbalanced datasets and improve your model performance.
-
Resampling techniques:Balance your dataset effectively by employing resampling methods. Oversampling can amplify minority class data, while undersampling reduces majority class data, achieving a more equitable distribution for better model accuracy.
-
Visualize the imbalance:Use graphical tools like scatter plots and box plots to spot disparities in your dataset. Visually assessing class distribution aids in recognizing imbalances early, allowing for timely corrective measures.
