A globally coupled map (GCM) model is a network of chaotic elements that are globally coupled with each other. In this paper, first, a modified GCM model called the globally coupled map using the symmetric map (S-GCM) is proposed. The S-GCM is designed for information-processing applications. The S-GCM has attractors called cluster frozen attractors , each of which is taken to represent...
Formation of a layered structure is studied in a globally coupled map of chaotic units with a plastic coupling strength that changes depending on the states of units globally and an external input. In the parameter region characterized by weakly chaotic and desynchronized dynamics, units spontaneously form a hierarchical structure due to the influence of the input. This hierarchical structure is not...
