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.

Making predictions in a notebook environment

If you took a day's (or a few days') break after the previous chapter, it's likely that your connection to the remote virtual machine ended. Because of that, you'll need to reconnect and start the API once again. There are ways to make your API always running, but that's out of the scope of this book. Furthermore, if you've moved the TPOT_Book_KeyPair.pem file to some other folder, you'll have to reset the permissions:

  1. With that in mind, execute the first command line from the following snippet, only if you have to reset the permissions:
    > chmod 400 TPOT_Book_KeyPair.pem
    > ssh -i "TPOT_Book_KeyPair.pem" [email protected]
    > cd api
    > python3 app.py
  2. Your API is running now. The next step is to open a JupyterLab or Jupyter Notebook environment and make a request. You'll need the requests library to do so, so here's how to import...
