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.

Training a continuous detector

In the previous chapter, you configured a detector in backtest mode. You will now configure the same detector in live mode. You already created a role and uploaded all the necessary data. To review these steps and make sure you have everything ready, you can review the detector creation steps in Chapter 14, Creating and Activating a Detector.

Configuring a detector in continuous mode

To build your live detector, complete the following steps:

  1. Log into your AWS console and search for Lookout for Metrics in the search bar at the top. Then, click on Amazon Lookout for Metrics and go to the service home page.
  2. Click on the Create detector button on the right side of the screen. You will land on a page listing all the detectors visible from your AWS account. Click on the Create detector button at the top right.
  3. After a reminder to check the AWS region you are going to create a detector in, you are asked to provide a name for your detector...
