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.

Deploying models on inference pipelines

Real-life ML scenarios often involve more than one model; for example, you may need to run preprocessing steps on incoming data or reduce its dimensionality with the Principal Component Analysis (PCA) algorithm.

Of course, you could deploy each model to a dedicated endpoint. However, orchestration code would be required to pass prediction requests to each model in sequence. Multiplying endpoints would also introduce additional costs.

Instead, inference pipelines let you deploy up to five models on the same endpoint or for batch transform and automatically handle the prediction sequence.

Let's say that we wanted to run PCA and then Linear Learner. Building the inference pipeline would look like this:

  1. Train the PCA model on the input dataset.
  2. Process the training and validation sets with PCA and store the results in S3. batch transform is a good way to do this.
  3. Train the Linear Learner model using the datasets processed...
