Machine Learning Automation with TPOT

By: Dario Radečić

Overview of this book

The automation of machine learning tasks allows developers more time to focus on the usability and reactivity of the software powered by machine learning models. TPOT is a Python automated machine learning tool used for optimizing machine learning pipelines using genetic programming. Automating machine learning with TPOT enables individuals and companies to develop production-ready machine learning models cheaper and faster than with traditional methods. With this practical guide to AutoML, developers working with Python on machine learning tasks will be able to put their knowledge to work and become productive quickly. You'll adopt a hands-on approach to learning the implementation of AutoML and associated methodologies. Complete with step-by-step explanations of essential concepts, practical examples, and self-assessment questions, this book will show you how to build automated classification and regression models and compare their performance to custom-built models. As you advance, you'll also develop state-of-the-art models using only a couple of lines of code and see how those models outperform all of your previous models on the same datasets. By the end of this book, you'll have gained the confidence to implement AutoML techniques in your organization on a production level.

Applying automated regression modeling to the vehicle dataset

This section shows how to develop an automated machine learning model on the most complex dataset thus far. You will use the vehicle dataset (https://www.kaggle.com/nehalbirla/vehicle-dataset-from-cardekho), so download it if you haven't already. The goal is to predict the selling price based on the various predictors, such as year made and kilometers driven.

This time, we won't focus on exploratory data analysis. You can do that on your own if you've followed the last two examples. Instead, we'll concentrate on dataset preparation and model training. There's a lot of work required to transform this dataset into something ready for machine learning, so let's get started right away:

  1. Once again, the first step is to load in the libraries and the dataset. The requirements are the same as with previous examples. You'll need numpy, pandas, matplotlib, and seaborn. Here's how...
