Learn Unity ML-Agents ??? Fundamentals of Unity Machine Learning

Overview of this book

Unity Machine Learning agents allow researchers and developers to create games and simulations using the Unity Editor, which serves as an environment where intelligent agents can be trained with machine learning methods through a simple-to-use Python API. This book takes you from the basics of Reinforcement and Q Learning to building Deep Recurrent Q-Network agents that cooperate or compete in a multi-agent ecosystem. You will start with the basics of Reinforcement Learning and how to apply it to problems. Then you will learn how to build self-learning advanced neural networks with Python and Keras/TensorFlow. From there you move o n to more advanced training scenarios where you will learn further innovative ways to train your network with A3C, imitation, and curriculum learning models. By the end of the book, you will have learned how to build more complex environments by building a cooperative and competitive multi-agent ecosystem.

Preface

Machine learning (ML) has been described as the next technological wave to hit humankind, akin to that of electricity. While this is a big claim, we can make certain analogies between the two technologies. For one, you really don't need to understand the inner workings of electricity to use it, and in some ways that applies to ML and many of the more advanced concepts. If you wire up a light the wrong way, it won't work, or you could hurt yourself, and the same analogy applies to machine learning. You still need enough knowledge to call yourself an MLtician or ML practitioner (if you will), and it is the goal of this book to give you that depth of knowledge. Now, the area of ML is broad, so our focus in this book will be to use deep reinforcement learning (DRL) in the form of Unity ML-Agents. DRL is currently a hot topic for developing robotic and simulation agents in many areas, and it is certainly a great addition to the Unity platform.
