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.

The project

With all that done, it's time to get on to the project! Once again, we are going to recognize handwritten digits. But this time around, we're going to build a CNN for that. Instead of just using the tensor package of Gorgonia, this time we're going to use all of Gorgonia.

Once again, to install Gorgonia, simply run go get -u gorgonia.org/gorgonia and go get -u gorgonia.org/tensor.

Getting the data

The data is the same data as in the previous chapter: the MNIST dataset. It can be found in the repository for this chapter, and we'll be using a function we wrote in the previous chapter to acquire the data:

// Image holds the pixel intensities of an image.
// 255 is foreground (black), 0 is background...
