Go Machine Learning Projects

By: Xuanyi Chew

Overview of this book

Go is the perfect language for machine learning; it helps to clearly describe complex algorithms, and also helps developers to understand how to run efficient optimized code. This book will teach you how to implement machine learning in Go to make programs that are easy to deploy and code that is not only easy to understand and debug, but also to have its performance measured. The book begins by guiding you through setting up your machine learning environment with Go libraries and capabilities. You will then plunge into regression analysis of a real-life house pricing dataset and build a classification model in Go to classify emails as spam or ham. Using Gonum, Gorgonia, and STL, you will explore time series analysis along with decomposition and clean up your personal Twitter timeline by clustering tweets. In addition to this, you will learn how to recognize handwriting using neural networks and convolutional neural networks. Lastly, you'll learn how to choose the most appropriate machine learning algorithms to use for your projects with the help of a facial detection project. By the end of this book, you will have developed a solid machine learning mindset, a strong hold on the powerful Go toolkit, and a sound understanding of the practical implementations of machine learning algorithms in real-world projects.

Naive Bayes

The classifier is a Naive Bayes classifier. To break it down, Naive in the phrase Naive Bayes means that we are assuming that all the input features are independent. To understand how the classifier works, an additional component needs to be introduced first: the term frequency-inverse frequency (TF-IF) pair of statistics.

TF-IDF

TF-IDF, per its namesake, is comprised of two statistics: term frequency (TF) and inverse document frequency (IDF).

The central thesis to TF is that if a word (called a term) occurs many times in a document, it means that the document revolves more around that word. It makes sense; look at your emails. The keywords typically revolve around a central topic. But TF is a lot more simplistic...
