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.

Variation points – alternatives and extensions to the fundamental workflow

The fundamental workflow we developed here is a simple example. For each step we performed, there are multiple alternatives and extensions to what has been shown. All of Part 2:, Building State-of-the-Art Models at Scale, is dedicated to understanding these alternatives and elaborations and to putting them together to build superior models at scale.

Let's first touch on some key variation points here.

Launching an H2O cluster using the Enterprise Steam API versus the UI (step 1)

In our example, we used the convenience of the Enterprise Steam UI to configure and launch an H2O cluster. Alternatively, we could have used the Steam API from our IDE to do so. See the full H2O Enterprise Steam API documentation at https://docs.h2o.ai/enterprise-steam/latest-stable/docs/python-docs/index.html for the Python API and https://docs.h2o.ai/enterprise-steam/latest-stable/docs/r-docs/index.html for the...
