Learn Amazon SageMaker - Second Edition

By: Julien Simon

Overview of this book

Amazon SageMaker enables you to quickly build, train, and deploy machine learning models at scale without managing any infrastructure. It helps you focus on the machine learning problem at hand and deploy high-quality models by eliminating the heavy lifting typically involved in each step of the ML process. This second edition will help data scientists and ML developers to explore new features such as SageMaker Data Wrangler, Pipelines, Clarify, Feature Store, and much more. You'll start by learning how to use various capabilities of SageMaker as a single toolset to solve ML challenges and progress to cover features such as AutoML, built-in algorithms and frameworks, and writing your own code and algorithms to build ML models. The book will then show you how to integrate Amazon SageMaker with popular deep learning libraries, such as TensorFlow and PyTorch, to extend the capabilities of existing models. You'll also see how automating your workflows can help you get to production faster with minimum effort and at a lower cost. Finally, you'll explore SageMaker Debugger and SageMaker Model Monitor to detect quality issues in training and production. By the end of this Amazon book, you'll be able to use Amazon SageMaker on the full spectrum of ML workflows, from experimentation, training, and monitoring to scaling, deployment, and automation.

Monitoring prediction quality with Amazon SageMaker Model Monitor

SageMaker Model Monitor has two main features, outlined here:

  • Capturing data sent to an endpoint, as well as predictions returned by the endpoint. This is useful for further analysis, or to replay real-life traffic during the development and testing of new models.
  • Comparing incoming traffic to a baseline built from the training set, as well as sending alerts about data quality issues, such as missing features, mistyped features, and differences in statistical properties (also known as "data drift").

We'll use the Linear Learner example from Chapter 4, Training Machine Learning Models, where we trained a model on the Boston Housing dataset. First, we'll add data capture to the endpoint. Then, we'll build a baseline and set up a monitoring schedule to periodically compare the incoming data to that baseline.
