Hands-On Machine Learning with ML.NET

By: Jarred Capellman

Overview of this book

Machine learning (ML) is widely used in many industries such as science, healthcare, and research and its popularity is only growing. In March 2018, Microsoft introduced ML.NET to help .NET enthusiasts in working with ML. With this book, you’ll explore how to build ML.NET applications with the various ML models available using C# code. The book starts by giving you an overview of ML and the types of ML algorithms used, along with covering what ML.NET is and why you need it to build ML apps. You’ll then explore the ML.NET framework, its components, and APIs. The book will serve as a practical guide to helping you build smart apps using the ML.NET library. You’ll gradually become well versed in how to implement ML algorithms such as regression, classification, and clustering with real-world examples and datasets. Each chapter will cover the practical implementation, showing you how to implement ML within .NET applications. You’ll also learn to integrate TensorFlow in ML.NET applications. Later you’ll discover how to store the regression model housing price prediction result to the database and display the real-time predicted results from the database on your web application using ASP.NET Core Blazor and SignalR. By the end of this book, you’ll have learned how to confidently perform basic to advanced-level machine learning tasks in ML.NET.

Creating the logistic regression application

As mentioned earlier, the application we will be creating to demonstrate logistic regressions is a file classifier. Given a file (of any type), we extract the strings from the file. This is a very common approach to performing file classification although, like the previous example, this is often just an element of file classification, not the only component. Therefore, don't expect this to find the next zero-day piece of malware!

The completed project code, sample dataset, and project files can be downloaded here: https://github.com/PacktPublishing/Hands-On-Machine-Learning-With-ML.NET/tree/master/chapter03_logistic_regression.

The trainer used in this application also uses SDCA but using the logistic regression variation that was discussed earlier in this chapter.

As in the previous example, we will begin by exploring the project architecture, diving into the code, and then show how you can run the example to both train and predict.
