How does Handling Imbalanced Datasets work

Beginner

Answer

Techniques include oversampling the rare class, undersampling the common class, or using specialized algorithms and evaluation metrics designed to handle uneven class sizes.
Real-world example A fraud detection dataset with very few fraud cases compared to normal transactions uses oversampling to help the model learn to detect fraud more reliably.
