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 6: Training Natural Language Processing Models

In the previous chapter, you learned how to use SageMaker's built-in algorithms for Computer Vision (CV) to solve problems including image classification, object detection, and semantic segmentation.

Natural Language Processing (NLP) is another very promising field in machine learning. Indeed, NLP algorithms have proven very effective in modeling language and extracting context from unstructured text. Thanks to this, applications such as search, translation, and chatbots are now commonplace.

In this chapter, you will learn about built-in algorithms designed specifically for NLP tasks. We'll discuss the types of problems that you can solve with them. As in the previous chapter, we'll also cover in great detail how to prepare real-life datasets such as Amazon customer reviews. Of course, we'll train and deploy models too. We will cover all of this under the following topics:

  • Discovering the NLP...
