Introduction
In the previous chapter, we began our supervised machine learning journey using regression techniques, predicting the continuous variable output given a set of input data. We will now turn to the other sub-type of machine learning problems that we previously described: classification problems. Recall that classification tasks aim to predict, given a set of input data, which one of a specified number of groups of classes data belongs to.
In this chapter, we will extend the concepts learned in Chapter 3, Regression Analysis, and will apply them to a dataset labeled with classes, rather than continuous values, as output.
