Customer churn refers to the situation when a customer ends their relationship with a company, and it’s a costly problem. Loss of customers impacts sales of a company. This model can be used by companies to predict the probability of a customer leaving the company. The model is trained on the data of a telecommunications company Telco which is concerned about the number of customers leaving their landline business for cable competitors. Imagine that you’re an analyst at this company and you have to find out who is leaving.
