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 Metrics?

Amazon Lookout for Metrics is one of the AI/ML managed services available on the AWS cloud platform. This service finds anomalies in your live real-time data, helps you pinpoint their root causes, and continuously improves by collecting your feedback. This service connects to your data sources and lets you create detectors that will monitor values from your data sources. Amazon Lookout for Metrics develops an understanding of your data over time to better capture anomalies. You can either let the service learn from the live data it starts analyzing when you connect a datasource (this training period might take from a few minutes to a day), or provide some historical training data to kickstart the learning process. Under the hood, Lookout for Metrics can leverage multiple algorithms and will select the best one based on your data.
