📊 Customer Churn Prediction – Analytics & Machine Learning Project
📌 Project Overview
Customer churn is a critical business challenge in the telecom industry. This project focuses on analyzing customer data to identify key factors influencing churn and building a machine learning–based solution to support data-driven decision making.
The objective is to demonstrate an end-to-end analytics workflow—from data exploration and insight generation to model development and deployment—while maintaining a strong focus on business relevance and interpretability.
🎯 Objectives
Analyze customer behavior to understand why customers churn
Perform exploratory data analysis (EDA) to uncover trends and patterns
Build classification models to predict churn
Translate analytical results into clear, actionable insights
Demonstrate how analytics and ML can support operational intelligence
Deploy the solution for interactive prediction
