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.

Ingesting data in Amazon Forecast

We are going to ingest our three datasets one by one to populate a complete dataset group: a target dataset that we are going to forecast for, a related time series dataset, and an item metadata dataset.

Ingesting your target time series dataset

At the end of the dataset group creation, you are automatically brought to the target time series dataset creation. If you stop the process after the dataset group creation and want to access this ingestion screen later from the Amazon Forecast home page, you just need to click on your dataset group name to view this dashboard.

From there, you can click on the Import button next to the Target time series data label. To create your target time series dataset, you will need to feed in dataset details and the import details.
