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 train your first anomaly detection model with Amazon Lookout for Equipment. Using the dataset you created in the previous chapter, you were able to configure and train a model.

One of the key things you learned from this chapter is how Amazon Lookout for Equipment leverages provided optional labels. Although the service only uses unsupervised models under the hood, these label ranges are used to rank the ones that are best at finding abnormal behaviors located within these ranges.

Last but not least, we took a deep dive into how to read the evaluation dashboard of a trained model and how valuable it can be to go beyond the raw results that are provided by the service.

In the next chapter, you are going to learn how to use your trained model to run regularly scheduled inferences on fresh data.
