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.

k-nearest neighbors

Moving on from logistic regression, let's try our first non-regression model, k-nearest neighbors (kNN). kNN is also a simple classification model, and it's one of the easiest model algorithms to grasp. It follows on from the basic premise that if I want to classify a record, I should consider other similar records.

kNN is implemented in multiple existing Go packages including github.com/sjwhitworth/golearn, github.com/rikonor/go-ann, github.com/akreal/knn, and github.com/cdipaolo/goml. We will be using the github.com/sjwhitworth/golearn implementation, which will serve as a great introduction to using github.com/sjwhitworth/golearn in general.

As mentioned, kNN operates on the...
