| Outline of Final Research Achievements |
A novel information processing method based on delayed dynamical systems (DDSs) has been proposed, which is called reservoir computing (RC). In delay-based RC, a DDS is regarded as a recurrent neural network composed of many coupled nodes and virtual
nodes are considered in the feedback delay loop by time-multiplexing. In this study, we numerically and experimentally demonstrate RC based on mutually-delay coupled optoelectronic system. We consider N virtual nodes in each two systems, which results in 2N virtual nodes. To produce diifferent node states in each systems, we use feedback delay loops with different delay times. We applied a chaotic time-series prediction task to evaluate the processing performance of our system. It is found that our RC system can produce higher prediction accuracy than RC based on
a single optoelectronic system.
