Hands-On Neuroevolution with Python

By: Iaroslav Omelianenko

Overview of this book

Neuroevolution is a form of artificial intelligence learning that uses evolutionary algorithms to simplify the process of solving complex tasks in domains such as games, robotics, and the simulation of natural processes. This book will give you comprehensive insights into essential neuroevolution concepts and equip you with the skills you need to apply neuroevolution-based algorithms to solve practical, real-world problems. You'll start with learning the key neuroevolution concepts and methods by writing code with Python. You'll also get hands-on experience with popular Python libraries and cover examples of classical reinforcement learning, path planning for autonomous agents, and developing agents to autonomously play Atari games. Next, you'll learn to solve common and not-so-common challenges in natural computing using neuroevolution-based algorithms. Later, you'll understand how to apply neuroevolution strategies to existing neural network designs to improve training and inference performance. Finally, you'll gain clear insights into the topology of neural networks and how neuroevolution allows you to develop complex networks, starting with simple ones. By the end of this book, you will not only have explored existing neuroevolution-based algorithms, but also have the skills you need to apply them in your research and work assignments.

Deep Neuroevolution

In this chapter, you will learn about the deep neuroevolution method, which can be used to train Deep Neural Networks (DNNs). DNNs are conventionally trained using backpropagation methods based on the descent of the error gradient, which is computed with respect to the weights of the connections between neural nodes. Although gradient-based learning is a powerful technique that conceived the current era of deep machine learning, it has its drawbacks, such as long training times and enormous computing power requirements.

In this chapter, we will demonstrate how deep neuroevolution methods can be used for reinforcement learning and how they considerably outperform traditional DQN, A3C gradient-based learning methods of training DNNs. By the end of this chapter, you will have a solid understanding of deep neuroevolution methods, and you'll also have practical...
