## Telecom Customer Churn Prediction: End-to-End MLOps Practice Guide

This project is an end-to-end machine learning solution addressing the pain point of customer churn in the telecom industry. It predicts customer churn risk using gradient boosting models and integrates a complete MLOps pipeline with Streamlit interactive dashboards, DVC data version control, MLflow experiment tracking, and Kubernetes containerized deployment, achieving a closed loop from data exploration to production-grade deployment.

## Business Background: Importance of Churn Prediction and Dataset Description

Customer churn is a costly operational pain point in the telecom industry—acquiring new customers costs 5-7 times more than retaining existing ones. Traditional post-hoc remediation strategies have limited effectiveness; proactively identifying at-risk customers and intervening early is key. The dataset for this project covers multi-dimensional information of 7043 customers (demographics, service subscriptions, billing, contract types, etc.), providing a foundation for model analysis.

## Technical Approach: Data Processing, Model Training, and Performance

### Data Processing and Feature Engineering
Raw data is cleaned (e.g., type conversion and missing value handling for the `TotalCharges` column) and several features are derived: tenure_group (tenure grouping), num_services (number of services), is_longterm (long-term contract flag), has_support (technical support subscription), charges_per_month (average monthly charges), is_high_value (high-value customer flag), etc.
### Model Selection and Performance
The gradient boosting machine (GBM) is used to adapt to tabular data, and SMOTE is applied to address class imbalance. Model performance on the test set: accuracy ≥88%, AUC-ROC ≥0.85, recall rate for churned customers ≥71%, precision ≥76%, which can support effective intervention strategies.

## Customer Segmentation: From Prediction to Targeted Retention Strategies

Customers are divided into 4 groups using K-Means clustering:
1. **Loyal Long-term Users**: Long tenure, annual contracts, low churn risk—suggest upselling premium services;
2. **New High-Spending Users**: Short tenure, high monthly spending, extremely high churn risk—need exclusive initial offers and VIP services;
3. **Economical Monthly Users**: Low monthly spending, pay-as-you-go, medium churn risk—suggest contract upgrade incentives;
4. **Stable Mid-Tier Users**: Medium tenure, multiple service subscriptions, low churn risk—suggest cross-selling support service packages.

## MLOps Practice: From Experiment to Production Deployment

### Data and Model Version Control
Using DVC + DagsHub to implement data/model versioning to ensure experiment reproducibility.
### Experiment Tracking
MLflow records experiment parameters and metrics, and registers the best model.
### Containerization and Deployment
Docker packages the application to ensure environment consistency; Kubernetes orchestration achieves high availability (auto-scaling, self-healing); GitHub Actions CI/CD automates the process: code push → data pull → training → validation → Docker build → K8s update.

## Streamlit Interactive Dashboard: An Intuitive Tool for Business Users

The Streamlit dashboard includes five modules:
- **Overview Panel**: Displays churn rate, contract distribution, and revenue impact;
- **EDA Module**: Interactive filtering and feature distribution charts;
- **Churn Predictor**: Inputs customer information and returns risk scores and driving factors;
- **Segmentation Visualization**: PCA dimensionality reduction to show cluster distribution;
- **Revenue Simulator**: Simulates the revenue impact of retention strategies. It has been deployed to Streamlit Cloud for direct use by business users.

## Key Findings and Business Recommendations: Driving Retention Rate Improvement

### Key Findings (SHAP Analysis)
1. Contract type: Monthly contract customers have 3x higher churn rate than annual contract customers;
2. Tenure: Churn risk is highest in the first 12 months of service;
3. Monthly spending: Customers with high spending but low perceived value are prone to churn.
### Business Recommendations
- Promote long-term contracts and incentivize monthly contract users to upgrade;
- Design a "new user care" program to reach new users at key touchpoints;
- Provide personalized services for high-spending users. It is expected to reduce overall churn rate by 10-15% and increase high-value customer retention rate by 20%+.
