How can I improve the accuracy of my machine learning model with imbalanced data?
Asked on Jan 19, 2026
Answer
Improving the accuracy of a machine learning model with imbalanced data involves techniques to handle the skewed distribution of classes. This can be achieved through data-level and algorithm-level strategies.
Example Concept: One common approach to address imbalanced data is to use resampling techniques such as oversampling the minority class or undersampling the majority class. Oversampling can be done by duplicating samples or using methods like SMOTE (Synthetic Minority Over-sampling Technique), which generates synthetic examples. Alternatively, algorithm-level methods like adjusting class weights or using ensemble methods such as Random Forests or Gradient Boosting can help the model focus more on the minority class.
Additional Comment:
- Consider using cross-validation to ensure that your resampling strategy is effective across different subsets of data.
- Evaluate your model using metrics suitable for imbalanced data, such as precision, recall, F1-score, or the area under the ROC curve (AUC-ROC), rather than just accuracy.
- Experiment with different algorithms and hyperparameters, as some models may inherently handle imbalance better than others.
- Feature engineering and selection can also play a critical role in improving model performance on imbalanced datasets.
