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.

Exploring models with SageMaker Debugger

SageMaker Debugger lets you configure debugging rules for your training job. These rules will inspect its internal state and check for specific unwanted conditions that could be developing during training. SageMaker Debugger includes a long list of built-in rules (https://docs.aws.amazon.com/sagemaker/latest/dg/debugger-built-in-rules.html), and you can add your own written in Python.

In addition, you can save and inspect the model state (gradients, weights, and so on) as well as the training state (metrics, optimizer parameters, and so on). At each training step, the tensors storing these values may be saved in near-real-time in an S3 bucket, making it possible to visualize them while the model is training.

Of course, you can select the tensor collections that you'd like to save, how often, and so on. Depending on the framework you use, different collections are available. You can find more information at https://github.com/awslabs...
