摘要:
Physical reservoir computing (RC) mimics the brain's capacity for temporal processing by mapping inputs into high-dimensional feature spaces. This biologically inspired approach offers advantages in terms of training efficiency and real-time performance. To enhance physical RC's accuracy, nonlinear and dynamic responses are essential to distinguish complex time-series input data. Here, we present a sodium-doped perovskite memristor-based RC system that capitalizes on the synergistic effects of photovoltaic and photogating to induce nonlinear an...
