Business Use CaseChurn Prediction
Main LanguagePython
Repository TypeGitHub
Overview & Objectives
This GitHub project focuses on predicting whether a bank customer is likely to churn. It is relevant for the portfolio because it shows practical machine learning skills for a real business problem: customer retention.
Project Goal
Build a classification model that helps identify customers at risk of leaving the bank.
The Business Problem
Banks need to identify customers who are likely to leave so they can take action earlier. The challenge was to prepare customer data and build a classification model that can separate churn risk from non-churn customers.
Methodology
My Approach
- 1Prepared customer churn data for machine learning.
- 2Handled numerical and categorical features.
- 3Trained classification models.
- 4Evaluated model performance with relevant metrics.
Implementation
