Hands-On Automated Machine Learning

By: Sibanjan Das, Umit Mert Cakmak

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.

Linearity versus non-linearity

Another consideration is decision boundaries. Some algorithms, such as logistic regression or Support Vector Machine (SVM), can learn linear decision boundaries while others, such as tree-based algorithms, can learn non-linear decision boundaries. While linear decision boundaries are relatively easy to calculate and interpret, you should be aware of errors that linear algorithms will generate in the presence of non-linear relationships.

Drawing decision boundaries

The following code snippet will allow you to examine the decision boundaries of different types of algorithms:

import matplotlib.cm as cm

# This function will scale training datatset and train given classifier.
# Based on predictions...
