Learn Amazon SageMaker

By: Julien Simon

Overview of this book

Amazon SageMaker enables you to quickly build, train, and deploy machine learning (ML) models at scale, without managing any infrastructure. It helps you focus on the ML problem at hand and deploy high-quality models by removing the heavy lifting typically involved in each step of the ML process. This book is a comprehensive guide for data scientists and ML developers who want to learn the ins and outs of Amazon SageMaker. You’ll understand how to use various modules of SageMaker as a single toolset to solve the challenges faced in ML. As you progress, you’ll cover features such as AutoML, built-in algorithms and frameworks, and the option for writing your own code and algorithms to build ML models. Later, the book will show you how to integrate Amazon SageMaker with popular deep learning libraries such as TensorFlow and PyTorch to increase the capabilities of existing models. You’ll also learn to get the models to production faster with minimum effort and at a lower cost. Finally, you’ll explore how to use Amazon SageMaker Debugger to analyze, detect, and highlight problems to understand the current model state and improve model accuracy. 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 predictions with Amazon SageMaker Model Monitor

SageMaker Model Monitor has two main features:

  • 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 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. Then, we'll build a baseline and set up a monitoring schedule to periodically compare the incoming data to that baseline.

Capturing data

We can set up the data capture process when we deploy an endpoint. We can also enable it...
