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.

What is Amazon Lookout for Equipment?

Amazon Lookout for Equipment is one of the AI/ML-managed services available on the AWS Cloud platform. This service leverages the data from sensors on your industrial equipment and automatically trains unsupervised ML models based on the specific data from this equipment without the requirement of any ML expertise. Amazon Lookout for Equipment analyzes your incoming sensor time series data to flag early warning signs (such as events) that could lead to an anomaly or a failure in your equipment or manufacturing process. Amazon Lookout for Equipment is asset agnostic. This means that beyond the time series data, you do not need to provide the characteristics of the process or equipment (for example, the make and model of the equipment, the units of measure of the time series data, the age of the asset, and more) that you are monitoring to use the service.

Managed services are services where only end-users bring their data and configure the parameters...
