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.

Configuring alerts

Amazon Lookout for Metrics finds anomalies in your data. Depending on the severity of the anomalies detected, the service can send some notifications either to a Lambda function or to an SNS topic:

  • AWS Lambda: This is a computing service that lets you run your code without provisioning and managing any underlying services or infrastructure. You can write a lambda function that will process any event generated by Amazon Lookout for Metrics to react to detected anomalies.
  • Amazon SNS: This messaging service can be used to send messages between applications or between applications and persons (for instance, by sending text messages to an end user). You can use this service to send a notification whenever your detector finds an anomaly worthy of being reported.

To add an alert to a detector, complete the following steps:

  1. Open the Amazon Lookout for Metrics service home page and click on Detectors in the left-hand menu bar. Then, select your...
