Overview of this book

AutoML is designed to automate parts of Machine Learning. Readily available AutoML tools are making data science practitioners’ work easy and are received well in the advanced analytics community. Automated Machine Learning covers the necessary foundation needed to create automated machine learning modules and helps you get up to speed with them in the most practical way possible. In this book, you’ll learn how to automate different tasks in the machine learning pipeline such as data preprocessing, feature selection, model training, model optimization, and much more. In addition to this, it demonstrates how you can use the available automation libraries, such as auto-sklearn and MLBox, and create and extend your own custom AutoML components for Machine Learning. By the end of this book, you will have a clearer understanding of the different aspects of automated Machine Learning, and you’ll be able to incorporate automation tasks using practical datasets. You can leverage your learning from this book to implement Machine Learning in your projects and get a step closer to winning various machine learning competitions.

Summary

In this chapter, you learned about many different aspects when it comes to choosing a suitable ML pipeline for a given problem.

Computational complexity, differences in training and scoring time, linearity versus non-linearity, and algorithm, specific feature transformations are valid considerations and it’s useful to look at your data from these perspectives.

You gained a better understanding of selecting suitable models and how machine learning pipelines work by practicing various use cases. You are starting to scratch the surface and this chapter was a good starting point to extend these skills.

In the next chapter, you will learn about optimizing hyperparameters and will be introduced to more advanced concepts, such as Bayesian-based hyperparameter optimization.
