Machine Learning at Scale with H2O

By: Gregory Keys, David Whiting

Overview of this book

H2O is an open source, fast, and scalable machine learning framework that allows you to build models using big data and then easily productionalize them in diverse enterprise environments. Machine Learning at Scale with H2O begins with an overview of the challenges faced in building machine learning models on large enterprise systems, and then addresses how H2O helps you to overcome them. You’ll start by exploring H2O’s in-memory distributed architecture and find out how it enables you to build highly accurate and explainable models on massive datasets using your favorite ML algorithms, language, and IDE. You’ll also get to grips with the seamless integration of H2O model building and deployment with Spark using H2O Sparkling Water. You’ll then learn how to easily deploy models with H2O MOJO. Next, the book shows you how H2O Enterprise Steam handles admin configurations and user management, and then helps you to identify different stakeholder perspectives that a data scientist must understand in order to succeed in an enterprise setting. Finally, you’ll be introduced to the H2O AI Cloud platform and explore the entire machine learning life cycle using multiple advanced AI capabilities. By the end of this book, you’ll be able to build and deploy advanced, state-of-the-art machine learning models for your business needs.

Chapter 4: H2O Model Building at Scale – Capability Articulation

So far, we have learned the fundamental workflow of how to build H2O models at scale, but that was done using H2O at its barest minimum. In this chapter, we will survey the extremely broad capability set of H2O model building at scale. We will then use our knowledge from this chapter and move on to part two, Building State-of-the-Art Models on Large Data Volumes Using H2O, where we will get down to business and use advanced techniques to build and explain highly predictive models at scale.

To conduct this survey, we will break down the chapter into the following main topics:

  • Articulating the H2O data capabilities during model building
  • Overviewing the H2O machine learning algorithms
  • Understanding the H2O modeling capabilities
