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.

Using H2O AutoML and Apache Storm

Apache Storm is an open source data analysis and computation tool for processing large amounts of stream data in real time. In the real world, you will often have plenty of systems that continuously generate large amounts of data. You may need to make some computations or run some processes on this data to extract useful information as it is generated in real time.

What is Apache Storm?

Let’s take the example of a log system in a very heavily used web service. Assuming that this web service receives millions of requests per second, it is going to generate tons of logs. And you already have a system in place that stores these logs in your database. Now, this log data will eventually pile up and you will have petabytes of log data stored in your database. Querying all this historical data to process it in one go is going to be very slow and time-consuming.

What you can do is process the data as it is generated. This is where Apache Storm...
