Why it matters

  • Class imbalance can significantly impact the performance of predictive models.
  • Measuring the class imbalance ratio helps select more appropriate evaluation metrics.
  • Awareness of the extent of class imbalance guides the choice of model and data preprocessing techniques.
  • While class imbalance is inherent to certain problems, it is important to continuously measure the class imbalance ratio to ensure that it does not go out of control.
