Stop Blaming Your Model: Your Imbalanced Dataset Is the Real Problem
📰 Medium · Python
Learn how imbalanced datasets can break even the best fraud detection models and what you can do to fix the issue
Action Steps
- Check your dataset for class imbalance using metrics like precision and recall
- Apply techniques like oversampling the minority class or undersampling the majority class to balance the dataset
- Use class weights or loss functions to account for imbalance during model training
- Evaluate your model's performance on a held-out test set to ensure it generalizes well
- Consider using metrics like F1-score or AUC-ROC to get a more accurate picture of model performance
