This chapter showed how business problems are faced by combining expertise and information. You saw how digital technologies led to an increment of the volume of information and provided us with new techniques to face challenges. You had an overview about the two most important branches of machine learning techniques: unsupervised and supervised learning. Unsupervised learning techniques identify some structures that are hidden in the data and supervised learning techniques use the data for estimating an unknown situation.

The next chapter shows the challenges related to machine learning problems and defines the requirements of software that identifies their solution. Then, the chapter introduces the software that we will be using in this book and provides you with a brief tutorial.
