Classification has traditionally been a type ofsupervised machine learning, which means it useslabeled datato train models. In supervised learning, each data point in the training data contains input variables (

In this chapter, we will take a tour through a selection of popular and powerful machine learning algorithms that are commonly used in academia as well as in industry. While learning about the differences between several supervised learning algorithms for classification, we will also develop an intu...
