Predict Customer Churn

• Project Predict Customer Churn in ML DevOps Engineer Nanodegree program by Udacity.

Project Description

Customer attrition, also known as customer churn, is the loss of clients or customers. Businesses measure and track churn as a percentage of lost customers compared to total number of customers over a given time period. Identifying and handling the customers about to churn can improve overall outcomes of the business.

This project seeks to answer the customer churn that is happening in the banking industry using clean code principles

The project is divided into the following sections:

• Import Data
• Exploratory data analysis and visualizations
• Feature engineering to transform data
• Building Models and evaulating performance
