* Gradient Boosting (e.g., XGBoost): Often provides the best performance on tabular data, which is typical for churn prediction. It also provides feature importance, aiding interpretability.
* Random Forest: Offers a good balance of performance and interpretability, and is less sensitive to feature scaling.
* Logistic Regression: Serves as an excellent baseline due to its simplicity and high interpretability, allowing us to compare more complex models against a clear benchmark.
We will prioritize performance while maintaining a reasonable level of interpretability. For critical decisions like churn, understanding why* a customer is predicted to churn is valuable. We will leverage techniques like SHAP (SHapley Additive exPlanations) or LIME (Local Interpretable Model-agnostic Explanations) to explain predictions from complex models.
* Consider stacking or weighted averaging of the best performing individual models (e.g., XGBoost and Random Forest) to potentially achieve marginal performance gains.
A well-defined pipeline ensures reproducible, efficient, and robust model development.
* Initial Split: 70% Training, 15% Validation, 15% Test.
* Training Set: Used to train the model.
* Validation Set: Used for hyperparameter tuning and model selection during development to prevent overfitting to the test set.
* Test Set: Held out completely and used only once at the end to evaluate the final model's performance on unseen data.
* Cross-Validation (on Training Set):
* Stratified K-Fold Cross-Validation: Essential for imbalanced datasets (like churn prediction) to ensure each fold has a similar proportion of target classes. Typically 5 or 10 folds.
* Time-Series Split (if applicable): If the data has a strong temporal component, use a time-based split (e.g., train on data up to month X, validate on month X+1).
