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.

H2O key concepts

In the following sections, we will identify and describe the key concepts of H2O that underlie the workflow steps of the previous section. These concepts are necessary to understand the rest of the book.

The data scientist's experience

The data scientist has a familiar experience in building H2O models at scale while being abstracted from the complexities of the infrastructure and architecture on the enterprise server cluster. This is further detailed in the following diagram:

Figure 2.2 – Details of the data scientist's experience with H2O Core

Data scientists use well-known unsupervised and supervised machine learning techniques that scale across the enterprise's distributed infrastructure and architecture. These techniques are written with the H2O model building API, which is written in familiar languages (such as Python, R, or Java) using familiar IDEs (for example, Jupyter or RStudio).
