🎯 Overview

Customer churn prediction is crucial for business success. This ML model helps identify customers likely to leave, enabling proactive retention strategies that:

• 💰 Reduce customer acquisition costs by 5-7x (retaining vs acquiring)
• 📈 Increase revenue through targeted retention campaigns
• 🎯 Improve customer lifetime value by identifying at-risk segments
• 📊 Data-driven decisions backed by interpretable ML insights

What Makes This Special?

✅ Multiple Algorithms: XGBoost, LightGBM, Random Forest, Gradient Boosting, Logistic Regression
✅ Production Ready: Easy deployment, batch predictions, REST API support
✅ Handles Imbalance: Built-in SMOTE implementation
✅ Interpretable: SHAP values, feature importance, risk scoring
✅ Well Documented: Comprehensive guides for data scientists and developers
✅ Extensible: Easy to customize and integrate with existing systems

🎬 Demo

Training a Model

# Train XGBoost model with default settings
python main.py --mode train --model xgboost

# Train with hyperparameter tuning (slower but better)
python main.py --mode train --model lightgbm --tune
