Speaking the Language of Data

You’ll often hear linear algebra referred to as the language of data. Recall from Chapter 2, ​Get Comfortable with Nx​, that Nx tensors give you a powerful and flexible abstraction for modeling and manipulating data. The power of Nx tensors and Nx operations comes from the fact that they build on existing theory and operations in linear algebra. Many of the algorithms you’ll see in this book rely heavily on established principles in linear algebra. Deep learning especially leans heavily on the power of linear algebra. In this section, you’ll get a quick feel for what linear algebra is all about, and you’ll see some linear algebra in action with Nx. This conversation is meant to serve only as an introduction to an ...
