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.

Creating an Amazon Forecast dataset group

As mentioned earlier, dataset groups are a convenient way to organize your datasets for each of your use cases or projects. Each dataset group is a collection of up to three datasets (one for each type: target time series, related time series, and metadata). For our energy consumption tutorial, we will have all three types of dataset present in the dataset group. To create your first forecasting project with Amazon Forecast, complete the following steps:

  1. Log in to your AWS console and search for Forecast in the search bar at the top.
  2. Click on Amazon Forecast to go to the service home page.
