Version: 2.2.0 Enterprise SaaS Edition
Last Updated: January 18, 2026
Status: Production Ready 🚀

- **Accuracy**: 99.99% - **Key Predictors** (SHAP analysis): 1. Payment Delay (strongest positive indicator) 2. Support Calls (high calls = churn risk) 3. Total Spend (inverse correlation) 4. Usage Frequency 5. Last Interaction

Explainability Insights

• SHAP: Payment delay and support calls are the most impactful features globally
• LIME: Individual predictions show consistent feature importance patterns
• Drift Monitoring: Reference vs production data comparison available in dashboard

🛠️ Preprocessing Recommendations

• Missing Values: Handle through imputation or removal as needed
• Categorical Encoding: Apply One-Hot or Ordinal encoding to categorical features
• Feature Scaling: Scale numeric features for distance-based and regularized models
• Class Imbalance: Consider resampling or class-weighted models if imbalance is detected
• Feature Engineering: Create interaction terms and polynomial features if needed

📊 Model Development Pipeline

1. Data Preparation: Load, clean, and preprocess data
2. Feature Engineering: Create and select relevant features
3. Train-Test Split: Split data (80-20 or as needed)
4. Model Training: Train Linear Regression and Random Forest models
5. Model Evaluation: Assess using MAE, MSE, R² metrics
6. Hyperparameter Tuning: Optimize model parameters (if needed)
7. Model Persistence: Save trained models with joblib for deployment
