Chapter 8
What Is Quantum Machine Learning?

Tell me and I forget. Teach me and I remember. Involve me and I learn.
— Benjamin Franklin

We now begin our journey through Quantum Machine Learning (QML). In this chapter, we will set the foundation for the remainder of this part of the book. We will begin by reviewing some general notions from classical machine learning, and then we will introduce the basic ideas that underlie QML as a whole.

We’ll cover the following topics in this chapter:

• The basics of machine learning

• Do you wanna train a model?

• Quantum-classical models

In this chapter, you will learn the basic principles behind general machine learning, and you will understand how to construct, train, and assess some simple classical models using industry-standard frameworks and tools. We will also present a general picture of the world of QML.
