Predict behavior to retain customers

Data from https://www.kaggle.com/blastchar/telco-customer-churn

Use-Case

Suppose we have a service for running marketing campaigns. For each customer, it needs to determine the probability of churn, and if it’s high enough, it will send a promotional email with discounts. Of course, this service needs to use our model to decide whether it should send an email.

Tested the working of the app

✅ Flask web service

✅ Docker

✅ AWS EC2 & Elastic Beanstalk

Method

we need to create a churn service — a service in Python that will serve the churn model. Given the features of a customer, it will respond with the probability of churn for this customer. For each customer, the campaign service will ask the churn service for the probability of churn, and if it’s high enough, then we send a promotional email

Steps

✅ Gets the customer data in a request

✅ Invokes predict_simple to score the customer

✅ Responds with the probability of churn in JSON

✅ Packaged the app with Docker and deployed using AWS Elastic Beanstalk

• Assigns the /predict route to the predict function

• Gets the content of the request in JSON

• Scores the customer

• Prepares the response

• Converts the response to JSON
