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.

Chapter 10: Advanced Training Techniques

In the previous chapter, you learned when and how to scale training jobs using features such as Pipe Mode and distributed training, as well as alternatives to S3.

In this chapter, we'll conclude our exploration of training techniques. You'll learn how to slash down your training costs with Managed Spot Training, how to squeeze every drop of accuracy from your models with Automatic Model Tuning, and how to crack models open with SageMaker Debugger.

This chapter covers the following topics:

  • Optimizing training costs with Managed Spot Training
  • Optimizing hyperparameters with Automatic Model Tuning
  • Exploring models with SageMaker Debugger
