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.

Introducing auto-sklearn

scikit-learn (also known as sklearn) is a very popular ML library for Python development – so popular that it has its own memes:

As part of this ecosystem and based on Efficient and Robust Automated Machine Learning by Feurer et al., auto-sklearn is an automated ML toolkit that performs algorithm selection and hyperparameter tuning using Bayesian optimizationmeta-learning, and ensemble construction.

The toolkit is available on GitHub to be downloaded: github.com/automl/auto-sklearn.

auto-sklearn touts its ease of use for performing automated ML since it's a four-line automated ML solution:

If the preceding syntax looks familiar, then it's because this is how scikit-learn does predictions and therefore makes auto-sklearn one of the easiest libraries to use. auto-sklearn uses...
