The HyperNEAT method exposes the fact that geometrical regularities of the natural world can be adequately represented by artificial neural networks with nodes placed at specific spatial locations. That way, the neuroevolution gains significant benefits and it allows large-scale ANNs to be trained for high dimensional problems, which was impossible with the ordinary NEAT algorithm. At the same time, the HyperNEAT approach is inspired by the structure of a natural brain, which still lacks the plasticity of the natural evolution process. While allowing the evolutionary process to elaborate on a variety of connectivity patterns between network nodes, the HyperNEAT approach exposes a hard limitation on where the network nodes are placed. The experimenter must define the layout of the network nodes from the very beginning, and any incorrect assumption...

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.
