Abstract
We have reported that a physical reservoir with a silver sulfide island network can classify simple patterns of an irradiated light without converting it to a voltage signal input. In this study, we conducted experiments to verify whether the detection of dynamical change in an irradiating light, e.g., moving in a reservoir layer, can be available. We also investigated the possibility that the reservoir could detect a position of light exposure, in addition to the dependence on the wavelength and the exposure time. The technique was applied to a task of whether character-shaped light patterns could be recognized even if the irradiated position was changed.
