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.

Section 2 – Building State-of-the-Art Models on Large Data Volumes Using H2O

This section dives deep into advanced techniques to build accurate and trusted ML models with large to massive data volumes using H2O. We first overview the full capability set of H2O-3 and Sparkling Water for model building. From there, we demonstrate these capabilities by engineering features, building and optimizing supervised learning models, building H2O models embedded in Spark pipelines, building unsupervised models using H2O algorithms, and reviewing how to update and ensure the reproducibility of H2O models. From there, we introduce in depth a number of methods for interpreting and understanding the decision-making process of your model and introduce auto-documentation within H2O. Finally, we do an extensive and thorough exercise in model building from problem statement and raw data through data cleaning, feature engineering, model building and optimization, and candidate model selection based...
