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.

Summary

In closing, it's only fair to mention that MachineBox does have some limitations for its free tiers; but for personal projects, in my experience, you won't run into them. Despite my personal reservations on the various machine learning-as-a-service systems out there, I do think they provide value. I have used them from time to time, but I generally do not need them. Nevertheless, I highly recommend that the reader check them out.

This chapter, in combination with the previous chapter, has shown the breadth of machine learning in the industry. Not all machine learning algorithms have to be handwritten from scratch if your main problem does not call for it. I am lucky enough to have a career in doing what I love: building customized machine learning algorithms. This may have tainted my views on this issue. You may be an engineer on a deadline who has to solve some...
