Outline of Final Research Achievements |
To detect weak signals below a threshold of a detector, the stochastic resonance (SR) is widely used, including fishes and crayfish. Also SR is used for the engineering applications like Schmitt triggers. To realize the SR system, the detecters are required to be driven independently. Usually, this is achieved by adding noises to detectors. For real systems, however, to add independent noises to many detectors has many difficulties. To avoid this problems, this study proposed an idea to use the asynchronous neural network as detecters. The asynchronous neural network are composed of excitatory and inhibitory neurons, and by adjusting connecting strength, the element cells can be independent each other. By computer simulations, we confirmed its usefulness.
