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 the NLP built-in algorithms in Amazon SageMaker

SageMaker includes four NLP algorithms, enabling supervised and unsupervised learning scenarios. In this section, you'll learn about these algorithms, what kind of problems they solve, and what their training scenarios are:

  • BlazingText builds text classification models (supervised learning)or computes word vectors (unsupervised learning). BlazingText is an Amazon-invented algorithm.
  • Latent Dirichlet Allocation (LDA) builds unsupervised learning models that group a collection of text documents into topics. This technique is called topic modeling.
  • Neural Topic Model (NTM) is another topic modeling algorithm based on neural networks, and it gives you more insight into how topics are built.
  • Sequence-to-sequence (seq2seq) builds deep learning models predicting a sequence of output tokens from a sequence of input tokens.
