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.

Orchestrating each step of the process with a serverless architecture

In the preceding chapters, you have been working mainly with the Amazon Lookout for Equipment console, building each step mostly manually. In this section, you will learn how you can build an automatic workflow that will take care of all these steps and inform you when it is finished. You will implement and deploy the components shown in the following screenshot:

To achieve this, we will focus on the implementation of each key part of this architecture diagram. Namely, we will dive into the following:

  1. First, you will get an overview of the AWS Step Functions orchestration service.
  2. Then you will build the key components of your Step Functions workflow (leveraging an AWS Lambda function and orchestrating the different Amazon Lookout for Equipment tasks).
  3. To trigger your workflow automatically, you will need...
