Overview of this book

Elastic Stack, previously known as the ELK stack, is a log analysis solution that helps users ingest, process, and analyze search data effectively. With the addition of machine learning, a key commercial feature, the Elastic Stack makes this process even more efficient. This updated second edition of Machine Learning with the Elastic Stack provides a comprehensive overview of Elastic Stack's machine learning features for both time series data analysis as well as for classification, regression, and outlier detection. The book starts by explaining machine learning concepts in an intuitive way. You'll then perform time series analysis on different types of data, such as log files, network flows, application metrics, and financial data. As you progress through the chapters, you'll deploy machine learning within Elastic Stack for logging, security, and metrics. Finally, you'll discover how data frame analysis opens up a whole new set of use cases that machine learning can help you with. By the end of this Elastic Stack book, you'll have hands-on machine learning and Elastic Stack experience, along with the knowledge you need to incorporate machine learning in your distributed search and data analysis platform.

Understanding inference processors and ingest pipelines

You have a trained machine learning model, so now what? Remember from Chapter 11, Classification Analysis, and Chapter 12, Regression, that one of the exciting things about machine learning models is that they learn from a labeled training dataset and then, in a way, encode the knowledge so that they can be used to make predictions on previously unseen data points. This process of labeling or making predictions for previously unseen data points is what we call inference.

How does this happen in practice in the Elastic Stack?

There are a multitude of different architectures that you might build to make use of inference in the Elastic Stack, but the basic building blocks of all of them are inference processors and ingest pipelines. These are the main subjects of our exploration in this chapter.

An ingest pipeline is a special component that lets you manipulate and transform your data in various ways before it is written...
