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.

Single time series forecasting

To illustrate the procedure of forecasting, we will start with a dataset that is a single time series. While this dataset is generic, you could imagine that it could represent a system performance metric, the number of transactions processed by a system, or even sales revenue data. The important aspect of this dataset is that it contains several distinct time-based trends—a daily trend, a weekly trend, and an overall increasing trend. Elastic ML will discover all three trends and will effectively predict those into the future. It is good to note that the dataset also contains some anomalies, but (of course) future anomalies cannot be predicted as they are surprise events by definition. Since our discussion here is purely focused on forecasting, we will ignore the existence of any anomalies found in our dataset while building the models for forecasting.

With that said, let’s jump into an example by using the forecast_example dataset from...
