Physical reservoir computing has been attracting attention in recent years. However, it remains unclear how much nonlinearity is required in the physical dynamics to achieve a high computational performance. Therefore, we focused on a resistor–capacitor circuit, which exhibits simple transient characteristics, and investigated the performance required for a physical reservoir. As a result, the proposed reservoir shows a high performance for time series prediction tasks and can be used as a computational resource even without high nonlinearity in the physical dynamics. These results are expected to help establish design guidelines that support the hardware implementation of physical reservoirs.

近年来，物理油藏计算引起了人们的关注。然而，目前尚不清楚物理动力学需要多少非线性才能实现高计算性能。因此，我们重点关注具有简单瞬态特性的电阻电容电路，并研究了物理储层所需的性能。因此，所提出的储层在时间序列预测任务中表现出高性能，并且即使在物理动力学中没有高度非线性的情况下也可以用作计算资源。这些结果预计将有助于建立支持物理油藏硬件实施的设计指南。
