3 Machine learning for classification

This chapter covers

• Performing exploratory data analysis for identifying important features
• Encoding categorical variables to use them in machine learning models
• Using logistic regression for classification

In this chapter, we are going to use machine learning to predict churn.

Churn is when customers stop using the services of a company. Thus, churn prediction is about identifying customers who are likely to cancel their contracts soon. If the company can do that, it can offer discounts on these services in an effort to keep the users.
