Introduction
In previous chapters, where an introduction to machine learning was covered, you were introduced to two broad categories of machine learning; supervised learning and unsupervised learning. Supervised learning can be further divided into two types of problem cases, regression and classification. In the last chapter, we covered regression problems. In this chapter, we will peek into the world of classification problems.
Take a look at the following Figure 3.1:

Classification problems are the most prevalent use cases you will encounter in the real world. Unlike regression problems, where a real numbered value is predicted, classification problems deal with associating an example to a category. Classification use cases will take forms such as the following:
- Predicting whether a customer will buy the recommended product
- Identifying whether a credit transaction is fraudulent ...
