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.

AutoML in Microsoft Azure

AutoML is treated as a first-class citizen in the Azure platform. The fundamental ideas behind feature engineering, network architecture search, and hyperparameter tuning are the same as what we discussed in Chapter 2, Automated Machine Learning, Algorithms, and Techniques, and Chapter 3, Automated Machine Learning with Open Source Tools and Libraries. However, the layer of abstraction that's used to democratize these skills makes them much more appealing to non-machine learning experts.

The key principles of AutoML in the Azure platform are shown in the following diagram. User input such as datasets target metrics, and constraints (how long to run the job, what the allocated budget is for compute, and so on) drive the AutoML "engine", which completes iterations to find the best model and rank it according to the score of Training Success:
