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.

Discovering the CV built-in algorithms in Amazon SageMaker

SageMaker includes three CV algorithms, based on proven deep learning networks. In this section, you'll learn about these algorithms, what kind of problem they can help you solve, and what their training scenarios are:

  • Image classification assigns one or more labels to an image.
  • Object detection detects and classifies objects in an image.
  • Semantic segmentation assigns every pixel of an image to a specific class.

Discovering the image classification algorithm

Starting from an input image, the image classification algorithm predicts a probability for each class present in the training dataset. This algorithm is based on the ResNet convolutional neural network (https://arxiv.org/abs/1512.03385). Published in 2015, ResNet won the ILSVRC classification task that same year (http://www.image-net.org/challenges/LSVRC/). Since then, it has become a popular and versatile choice for image classification...
