In this chapter, you learnt the basics of linear algebra, which is useful for machine learning, and the basic constructs like vectors and matrix. You also learnt how to use Spark and Breeze to do basic operations on these constructs. We looked at techniques like SVD to transform data. We also looked at the importance of the function types in linear algebra. In the end, you learnt how to plot basic charts using Breeze. In the next chapter, we will cover an overview of Machine Learning systems, components and architecture.
