Modularity and hierarchy
Another crucial aspect of how natural cognitive systems are organized is modularity and hierarchy. While studying the human brain, neuroscientists have found that it is not a monolithic system with a uniform structure, but rather a complex hierarchy of modular structures. Also, due to the speed limitations of signal propagation in the biological tissues, the structure of the brain enforces the principle of locality when related tasks are processed by geometrically adjacent structures in the brain. This aspect of natural systems did not escape the attention of researchers of neuroevolution and they are implemented in many evolutionary algorithms. We will discuss how modular ANNs can be created using a neuroevolution-based ...
