+# Customer Churn Prediction
+
+## Overview
+This project implements a machine learning solution to predict customer churn using three different algorithms: Random Forest, XGBoost, and Logistic Regression. The model helps identify customers who are likely to discontinue services, enabling proactive retention strategies.

+## Model Comparison
+
+### Performance Metrics
+
+| Model               | Accuracy | Precision | 
+|--------------------|----------|-----------|
+| Random Forest      | 0.87     | 0.83      | 
+| XGBoost            | 0.88     | 0.86      | 
+| Logistic Regression| 0.82     | 0.77      | 
+
+### Key Findings
+- XGBoost performed best overall with highest accuracy and AUC-ROC scores
+- Random Forest showed comparable performance with slightly lower metrics
+- Logistic Regression provided a good baseline but was outperformed by both ensemble methods
