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.

Chapter 4: Training Machine Learning Models

In the previous chapter, you learned how Amazon SageMaker Autopilot makes it easy to build, train, and optimize models automatically, without writing a line of machine learning code.

For problem types that are not supported by SageMaker Autopilot, the next best option is to use one of the algorithms already implemented in SageMaker and to train it on your dataset. These algorithms are referred to as built-in algorithms, and they cover many typical machine learning problems, from classification to time series to anomaly detection.

In this chapter, you will learn about built-in algorithms for supervised and unsupervised learning, what type of problems you can solve with them, and how to use them with the SageMaker SDK:

  • Discovering the built-in algorithms in Amazon SageMaker
  • Training and deploying models with built-in algorithms
  • Using the SageMaker SDK with built-in algorithms
  • Working with more built-in algorithms
  • ...
