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.

Chapter 12: Regression

In the previous chapter, we studied classification – one of the two supervised learning techniques available in the Elastic Stack. However, not all real-world applications of supervised learning lend themselves to the format required for classification. What if, for example, we wanted to predict the sales prices of apartments in our neighborhood? Or the amount of money a customer will spend in our online store? Notice that the value we are interested in here is not a discrete class, but instead is a value that can take a variety of continuous values in a range.

This is exactly the problem solved by regression analysis. Instead of predicting which class a given datapoint belongs to, we can predict a continuous value. Although the end goal is slightly different than that in classification, the underlying algorithm that is used for regression is the same as the one we examined for classification in the previous chapter. Thus, we already know a lot about...
