Building Machine Learning Systems with Python - Third Edition

By: Luis Pedro Coelho, Willi Richert, Matthieu Brucher

Overview of this book

Machine learning enables systems to make predictions based on historical data. Python is one of the most popular languages used to develop machine learning applications, thanks to its extensive library support. This updated third edition of Building Machine Learning Systems with Python helps you get up to speed with the latest trends in artificial intelligence (AI). With this guide’s hands-on approach, you’ll learn to build state-of-the-art machine learning models from scratch. Complete with ready-to-implement code and real-world examples, the book starts by introducing the Python ecosystem for machine learning. You’ll then learn best practices for preparing data for analysis and later gain insights into implementing supervised and unsupervised machine learning techniques such as classification, regression and clustering. As you progress, you’ll understand how to use Python’s scikit-learn and TensorFlow libraries to build production-ready and end-to-end machine learning system models, and then fine-tune them for high performance. By the end of this book, you’ll have the skills you need to confidently train and deploy enterprise-grade machine learning models in Python.

Getting Started with Python Machine Learning

Excelling at games

In the remainder of this chapter, we will use Q-games with the gym package. It offers a standard API for playing different types of games, so it's the perfect test case for what we want to show you.

A small example

Anaconda doesn't ship this package, so it has to be installed though pip:

>>> pip install gym[atari]
We won't use the Atari part of the gym, but it will be required for the breakout game.

From this package, we can create an environment for different games, like this:

env = gym.make('FrozenLake-v0')

This creates a new environment for the text game FrozenLake. It consists of four four-character strings, starting with S and ending up at G, the goal. But there are...
