Automated Machine Learning

Overview of this book

Every machine learning engineer deals with systems that have hyperparameters, and the most basic task in automated machine learning (AutoML) is to automatically set these hyperparameters to optimize performance. The latest deep neural networks have a wide range of hyperparameters for their architecture, regularization, and optimization, which can be customized effectively to save time and effort. This book reviews the underlying techniques of automated feature engineering, model and hyperparameter tuning, gradient-based approaches, and much more. You'll discover different ways of implementing these techniques in open source tools and then learn to use enterprise tools for implementing AutoML in three major cloud service providers: Microsoft Azure, Amazon Web Services (AWS), and Google Cloud Platform. As you progress, you’ll explore the features of cloud AutoML platforms by building machine learning models using AutoML. The book will also show you how to develop accurate models by automating time-consuming and repetitive tasks in the machine learning development lifecycle. By the end of this machine learning book, you’ll be able to build and deploy AutoML models that are not only accurate, but also increase productivity, allow interoperability, and minimize feature engineering tasks.

AWS SageMaker Autopilot

SageMaker Autopilot, as the name suggests, is a fully managed system that provides an automatic ML solution. The goal, as in any automated ML solution, is to try to offload most of the redundant and time-consuming, repetitive work to the machine while humans can do higher-level cognitive tasks. In the following diagram, you can see the parts of the ML life cycle that SageMaker Autopilot covers:

As part of the SageMaker ecosystem, SageMaker Autopilot is tasked with being the automated ML engine. A typical automated ML user flow is defined in the following figure, where a user analyzes the tabular data, selects the target prediction column, and then lets Autopilot do its magic of finding the correct algorithm. The secret sauce here is the underlying Bayesian optimizer as defined by Das et al. in their paper Amazon SageMaker Autopilot: a white box AutoML solution at scale (https://www.amazon...
