Time Series Analysis on AWS

By: Michaël Hoarau

Overview of this book

Being a business analyst and data scientist, you have to use many algorithms and approaches to prepare, process, and build ML-based applications by leveraging time series data, but you face common problems, such as not knowing which algorithm to choose or how to combine and interpret them. Amazon Web Services (AWS) provides numerous services to help you build applications fueled by artificial intelligence (AI) capabilities. This book helps you get to grips with three AWS AI/ML-managed services to enable you to deliver your desired business outcomes. The book begins with Amazon Forecast, where you’ll discover how to use time series forecasting, leveraging sophisticated statistical and machine learning algorithms to deliver business outcomes accurately. You’ll then learn to use Amazon Lookout for Equipment to build multivariate time series anomaly detection models geared toward industrial equipment and understand how it provides valuable insights to reinforce teams focused on predictive maintenance and predictive quality use cases. In the last chapters, you’ll explore Amazon Lookout for Metrics, and automatically detect and diagnose outliers in your business and operational data. By the end of this AWS book, you’ll have understood how to use the three AWS AI services effectively to perform time series analysis.

Summary

In this chapter, you learned how to prepare your historical data so that Amazon Lookout for Metrics can use it to perform backtesting. You also developed a good understanding of the e-commerce dataset that we will continue to use throughout this part dedicated to anomaly detection. You also got initial hands-on experience of Amazon Lookout for Metrics as you learned how to create a detector and how to connect it to a data source. You also learned how to configure an alert so that you can react when an anomaly is detected.

This chapter was key to understanding and manipulating the key concepts used by Amazon Lookout for Metrics (detectors, data source, alerts).

In the next chapter, you are going to switch your detector into a live detection mode and you are going to learn how to visualize the detected anomalies and provide feedback to the service.
