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 5: Training CV Models

In the previous chapter, you learned how to use SageMaker's built-in algorithms for traditional machine learning problems, including classification, regression, and anomaly detection. We saw that these algorithms work well on tabular data, such as CSV files. However, they are not well suited for image datasets, and they generally perform very poorly on CV (CV) tasks.

For a few years now, CV has taken the world by storm, and not a month goes by without a new breakthrough in extracting patterns from images and videos. In this chapter, you will learn about three built-in algorithms designed specifically for CV tasks. We'll discuss the types of problems that you can solve with them. We'll also spend a lot of time explaining how to prepare image datasets, as this crucial topic is often inexplicably overlooked. Of course, we'll train and deploy models too.

This chapter covers the following topics:

  • Discovering the CV built-in...
