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.

Breaking down matrix factorizations

As mentioned in Chapter 1, Getting Started with Machine Learning and ML.NET, matrix factorization, by definition, is an unsupervised learning algorithm. This means that the algorithm will train on data and build a matrix of patterns in user ratings, and during a prediction call, will attempt to find like ratings based on the data provided. In this section, we will dive into use cases for matrix factorization and have a look into the matrix factorization trainer in ML.NET.

Use cases for matrix factorizations

Matrix factorizations, as you might be starting to realize, have numerous applications where data is available, but the idea is to suggest other matches based on previously unselected data. Without needing to do manual spot-checking, matrix factorization algorithms train on this unselected data and determine patterns using a key-value pair combination. ML.NET provides various matrix factorization values to look at programmatically, inside of your...
