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.

Using your dataset to train a model

In the previous chapter, you created an Amazon Lookout for Equipment dataset and ingested your first time series dataset in it. You are now ready to train an anomaly detection model.

Training an anomaly detection model

To train an anomaly detection model with Amazon Lookout for Equipment, follow these steps:

  1. Log into your AWS console and search for Lookout for Equipment in the search bar at the top.
  2. Click on Amazon Lookout for Equipment to go to the service's home page:

  1. On this page, you can click on the hamburger icon (the one with three horizontal lines) at the top left to open the left panel, where you can click on Datasets. You will land on a page listing all the datasets that are visible from within your AWS account. You should see the dataset you created earlier (we named it industrial-pump). Click on your dataset's...
