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 datasets to train a predictor

By the end of Chapter 3, Creating a Project and Ingesting Your Data, you had ingested three datasets in a dataset group, called london_household_energy_consumption, as follows:

Figure 4.1 – The London household dataset group overview

From here, you are now going to train a predictor using these three datasets. To do so, from the Amazon Forecast home page, locate the View dataset groups button on the right-hand side and click on it. Then, click on the name of your project. This will display the main dashboard of your dataset group. From here, click on the Start button under the Predictor training label:

This will bring you to the predictor configuration screen. The first two sections are dedicated to the predictor's settings: in this chapter, you are only going to modify a few of these parameters, while the other ones...
