Summary

This chapter has given you a brief introduction into what machine learning is for those of you who are just beginning your journey into the world of machine learning. You have learned about how scikit-learn fits into the context of machine learning and how you can go about installing the necessary software. 

Finally, you had a brief glimpse at all the algorithms that you will learn to implement as you progress through this book, as well as its associated applications in the real world. 

In the next chapter, you will learn how to implement your first algorithm – the K-Nearest Neighbors algorithm!
