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.

Exporting and visualizing your forecasts

In this section, you will export your forecasts in CSV format and then visualize them on a spreadsheet.

Exporting the predictions

To export all the predictions associated with a generated forecast, you can follow these 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:
  3. Click on the View dataset groups button on the right side of the screen. You will land on a page listing all the dataset groups visible from your AWS account.
  4. Click on the name of the predictor you trained. Mine is called london_household_energy_consumption.
  5. On the left menu bar, click on Forecasts to bring up the list of forecasts generated with this dataset group.
  6. Click on the name of one of the forecasts you generated earlier. I will click on london_automl_20130701:
