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.

Summary

This chapter concludes our exploration of training techniques. You learned about managed spot training, a simple way to slash training costs by 70% or more. You also saw how checkpointing helps to resume jobs that have been interrupted. Then, you learned about automatic model tuning, a great way to extract more accuracy from your models by exploring hyperparameter ranges. You learned about SageMaker Debugger, an advanced capability that automatically inspects training jobs for unwanted conditions and saves tensor collections to S3 for inspection and visualization. Finally, we discovered two capabilities that help you build higher quality workflows and models, SageMaker Feature Store and SageMaker Clarify.

In the next chapter, we'll study model deployment in detail.
