Machine Learning With Go

Overview of this book

The mission of this book is to turn readers into productive, innovative data analysts who leverage Go to build robust and valuable applications. To this end, the book clearly introduces the technical aspects of building predictive models in Go, but it also helps the reader understand how machine learning workflows are being applied in real-world scenarios. Machine Learning with Go shows readers how to be productive in machine learning while also producing applications that maintain a high level of integrity. It also gives readers patterns to overcome challenges that are often encountered when trying to integrate machine learning in an engineering organization. The readers will begin by gaining a solid understanding of how to gather, organize, and parse real-work data from a variety of sources. Readers will then develop a solid statistical toolkit that will allow them to quickly understand gain intuition about the content of a dataset. Finally, the readers will gain hands-on experience implementing essential machine learning techniques (regression, classification, clustering, and so on) with the relevant Go packages. Finally, the reader will have a solid machine learning mindset and a powerful Go toolkit of techniques, packages, and example implementations.

Nonlinear and other types of regression

Although we have focused on linear regression in this chapter, you certainly are not limited to performing regression with linear formulas. You can model your dependent variable by one or more nonlinear terms such as powers, exponentials, or other transformations on your independent variables. For example, we could model Sales by a polynomial series of TV terms:

Keep in mind, however, that as you add this complexity, you are again putting yourself in danger of overfitting.

In terms of implementing non-linear regressions, you cannot use github.com/sajari/regression, which is limited to linear regression. However, go-hep.org/x/hep/fit allows you to fit or train certain nonlinear models, and there are other various people in the Go community that have, or are, developing other tools for nonlinear modeling.

There are also other linear regression...
