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.

Configuring a scheduler

In Chapter 9, Creating a Dataset and Ingesting Your Data, you prepared and ingested time series data in Amazon Lookout for Equipment. In Chapter 10, Training and Evaluating a Model, you used your dataset to train a new anomaly detection model. In this section, you are going to use this trained model to schedule regular inferences.

To configure a new scheduler once a model is trained, you will need to do the following:

  • Prepare your Amazon S3 bucket with an input and output location that will be used by your scheduler.
  • Configure and start your scheduler.

Let's dive into each of these in detail.

Preparing your Amazon S3 bucket

To prepare your Amazon S3 bucket for an Amazon Lookout for Equipment scheduler, follow these steps:

  1. If you went through the Technical requirements section at the beginning of this chapter, you should already be logged in to your AWS console, otherwise, fire up your favorite browser and log in to your...
