MBML Book Sample Code

Supporting code for the Model-Based Machine Learning book.

This project contains the sample code and test data for the freely-available book on model-based machine learning at http://mbmlbook.com/. The book introduces readers to how to build machine learning models for real-world problems. Each chapter tackles a different problem by defining a statistical model and demonstrating how to apply it to actual data. This repository contains the source code for these models together with the sample data - so that readers can run it on their own, re-create the results from the book and experiment with modifying the code.

Models here are created and applied using the Infer.NET framework. When targeting .NET Framework/Windows code produces visualizations using Glo.

Contents

Structure of Repository

  • The Visual Studio solution Samples.sln in the root of the repository contains a project with models for every chapter of the book and a few projects with the shared code and/or unit tests from the folders described below. Code layout in projects corresponding to the book chapters is similar and expanded only once.

  • src/

    • 1. A Murder Mystery - code by Thomas Diethe and Dmitry Kats/
    • 2. Assessing People's Skills - code by Thomas Diethe and Dmitry Kats/
      • Data - input data in ObjML format
      • DataObjects - .NET types to hold the input data
      • Experiment - types that facilitate experimentation: types for metrics, results, and, possibly, other experiment-related data structures; a type that represents a single experiment and exposes a method to run it, type(s) that store multiple experiments together for comparison, etc.
      • Models - .NET types for Infer.NET models. Have methods to construct a model and to run inference on it.
      • Views - additional Glo views needed for specific chapter. Not included in compilation when targeting .Net Core.
      • Contents.cs - static type that has constants for the name of the chapter and all the sections within the chapter
      • Program.cs
    • 3. Meeting Your Match - code by Thomas Diethe and Alexander Novikov
      • This chapter and the remaining chapters have similar layout to chapter 2.
    • 4. Uncluttering Your Inbox - code by Thomas Diethe and Dmitry Kats
    • 5. Making Recommendations - code by Yordan Zaykov and Alexander Novikov
    • 6. Understanding Asthma - code by John Guiver and Dmitry Kats
    • 7. Harnessing the Crowd - code by John Guiver and Dmitry Kats
    • MBMLCommon/ - a number of utility classes shared by different projects including
      • Outputter.cs - class that encapsulates outputting objects, so that the code for chapters can output results in a platform-agnostic way. Also exposes methods for saving outputs to .objml files.
    • MBMLViews - additional Glo views shared among the chapters.

  • test/ - projects with unit tests
