非线性动力系统作为储层的潜力在储层计算的物理实现中引起了广泛的关注。在这里，我们提出了一个硬件系统作为一个水库，具有一种简单的非线性形式，反映了材料的内在特性。我们表明，在外部控制的帮助下，这种物理系统的动力学不足可以像复杂的动力系统一样运行。基于空间复用的思想，在两种框架下对该动态系统进行了研究。提出了在处理各类任务时，水库结构调整与系统性能之间的相关性。我们的研究结果有望使基于材料的RC设备的发展成为可能。
The potential of nonlinear dynamical systems serving as reservoirs has attracted much attention for the physical realization of reservoir computing (RC). Here, we propose a hardware system working as a reservoir with one simple form of nonlinearity that reflects the intrinsic characteristics of the materials. We show that insufficient dynamics in such physical systems can perform like complex dynamical systems with the assistance of external controls. Based on the idea of spatial multiplexing, this dynamical system is studied under two frameworks. The correlation between structural adjustments of the reservoir and system performance in processing various types of task is proposed. Our results are expected to enable the development of material-based devices for RC.
