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.

Discovering Amazon SageMaker Ground Truth

Added to Amazon SageMaker in late 2018, Amazon SageMaker Ground Truth helps you quickly build accurate training datasets. Machine learning practitioners can distribute labeling work to public and private workforces of human labelers. Labelers can be productive immediately, thanks to built-in workflows and graphical interfaces for common image, video, and text tasks. In addition, Ground Truth can enable automatic labeling, a technique that trains a machine learning model able to label data without additional human intervention.

In this section, you'll learn how to use Ground Truth to label images and text.

Using workforces

The first step in using Ground Truth is to create a workforce, a group of workers in charge of labeling data samples.

Let's head out to the SageMaker console: in the left-hand vertical menu, we click on Ground Truth, then on Labeling workforces. Three types of workforces are available: Amazon Mechanical...
