摘要翻译：
尽管概念大相径庭，回声状态网络和压缩感知模型都依赖于随机权重的集合；作为回波状态网络的储层动力学，以及压缩感知中的感知系数。在压缩感知中，有几种生成随机矩阵和度量以指示期望性能的方法得到了很好的研究，但对回声状态网络的研究较少。这项工作探索了这些压缩感知方法和度量的任何重叠，以应用于回声状态网络。考虑了几种随机库权重的产生方法，并借鉴压缩感知的受限等距特性，提出了一种新的回声状态网络权重的产生方法。理论和实验结果表明，相同类型的随机矩阵适用于回声状态网络和压缩感知场景，当所提出的受限等距常数接近1时，回声状态网络的分类精度得到了提高。

英文摘要：
Although largely different concepts, echo state networks and compressed sensing models both rely on collections of random weights; as the reservoir dynamics for echo state networks, and the sensing coefficients in compressed sensing. Several methods for generating the random matrices and metrics to indicate desirable performance are well-studied in compressed sensing, but less so for echo state networks. This work explores any overlap in these compressed sensing methods and metrics for application to echo state networks. Several methods for generating the random reservoir weights are considered, and a new metric, inspired by the restricted isometry property for compressed sensing, is proposed for echo state networks. The methods and metrics are investigated theoretically and experimentally, with results suggesting that the same types of random matrices work well for both echo state network and compressed sensing scenarios, and that echo state network classification accuracy is improved when the proposed restricted isometry-like constants are close to 1.
