Practical Automated Machine Learning Using H2O.ai

By: Salil Ajgaonkar

Overview of this book

With the huge amount of data being generated over the internet and the benefits that Machine Learning (ML) predictions bring to businesses, ML implementation has become a low-hanging fruit that everyone is striving for. The complex mathematics behind it, however, can be discouraging for a lot of users. This is where H2O comes in – it automates various repetitive steps, and this encapsulation helps developers focus on results rather than handling complexities. You’ll begin by understanding how H2O’s AutoML simplifies the implementation of ML by providing a simple, easy-to-use interface to train and use ML models. Next, you’ll see how AutoML automates the entire process of training multiple models, optimizing their hyperparameters, as well as explaining their performance. As you advance, you’ll find out how to leverage a Plain Old Java Object (POJO) and Model Object, Optimized (MOJO) to deploy your models to production. Throughout this book, you’ll take a hands-on approach to implementation using H2O that’ll enable you to set up your ML systems in no time. By the end of this H2O book, you’ll be able to train and use your ML models using H2O AutoML, right from experimentation all the way to production without a single need to understand complex statistics or data science.

Exploring Optional Parameters for H2O AutoML

As we explored in Chapter 2, Working with H2O Flow (H2O’s Web UI), when training models using H2O AutoML, we had plenty of parameters to select. All these parameters gave us the capability to control how H2O AutoML should train our models. This control helps us get the best possible use of AutoML based on our requirements. Most of the parameters we explored were pretty straightforward to understand. However, there were some parameters whose purpose and effects were slightly complex to be understood at the very start of this book.

In this chapter, we shall explore these parameters by learning about the Machine Learning (ML) concepts behind them, and then understand how we can use them in an AutoML setting.

By the end of this chapter, you will not only be educated in some of the advanced ML concepts, but you will also be able to implement them using the parametric provisions made in H2O AutoML.

In this chapter, we will cover...
