Bank Customer Churn Prediction Machine Learning Model
By Artem Moshnin
Problem description
-
Some well-known bank has been observing a lot of customers closing their accounts or switching to competitor banks over the past couple of quarters.
-
This has caused a huge dent in their quarterly revenues and might drastically affect annual revenues for the ongoing financial year, causing stocks to plunge and market cap to reduce significantly.
-
The idea is to be able to predict which customers are going to churn so that necessary actions/interventions can be taken by the bank to retain such customers.
Problem description from data science perspective
-
To develop a solution for this churn prediction problem I have been using customer data pertaining to his past transactions with the bank and some demographic information.
-
I have used this customer data to establish relations/associations between data features & customers' propensity to churn by building a classification model to predict whether the customer will leave the bank or not.
-
Furthermore, with an objective of explaning model predictions, I have built multiple visualisations which give insight into which factors are responsible for the churn of the customers.
