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.

Summary

Regression is the second of the two supervised learning methods in the Elastic Stack. The goal of regression is to take a trained dataset (a dataset that contains some features and a dependent variable that we want to predict) and distill it into a trained model. In regression, the dependent variable is a continuous value, which makes it distinct from classification, which handles discrete values. In this chapter, we have made use of the Elastic Stack's machine learning functionality to use regression to predict the sales price of a house based on a number of attributes, such as the house's location and the number of bedrooms. While there are numerous regression techniques available, the Elastic Stack uses gradient boosted decision trees to train a model.

In the next chapter, we will take a look at how supervised learning models can be used together with inference processors and ingest pipelines to create powerful, machine learning-powered data analysis pipelines...
