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.

A model building and deployment view – the personas on the ground

Many personas or stakeholders are involved in the machine learning life cycle. The key personas involved in H2O at scale model building and deployment are the data scientist, the Enterprise Steam administrator, and the operations team. The focus of this chapter is on these personas. Let's get a high-level view of their activities as shown in the following diagram:

A summary of these stakeholders and their high-level concerns are as follows:

  • Enterprise Steam Administrator: Governs who launches H2O clusters on the multitenant enterprise server cluster and how many resources they are allowed to consume, and centralizes and manages H2O integration on the server cluster
  • H2O Cluster Operations: Troubleshoots H2O jobs on the enterprise server cluster (either a Kubernetes or Hadoop cluster...
