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.

Automated ML challenges and opportunities

We have discussed the benefits of automated ML, but all these advantages are not without their fair share of challenges. Automated ML is not a silver bullet and there are several scenarios where it would not work. The following are some challenges and scenarios where automated ML may not be the best fit.

Not having enough data

The size of the dataset is a critical component for automated ML to work well. When feature engineering, hyperparameter optimization, and neural architectural search are used on small datasets, they do not yield good results. The dataset has to be significantly large for automated ML tools to do their job effectively. If this is not the case with your dataset, you might want to try the alternative approach of building models manually.

Model performance

In a small number of cases, the performance you get from out-of-the-box models may not work – you may have to hand-tune the model for performance or...
