论文摘要
储层计算是预测湍流的有力工具，其简单的架构具有处理大型系统的计算效率。然而，其实现通常需要完整的状态向量测量和系统非线性知识。我们使用非线性投影函数将系统测量扩展到高维空间，然后将其输入到储层中以获得预测。我们展示了这种储层计算网络在时空混沌系统上的应用，该系统模拟了湍流的若干特征。我们表明，使用径向基函数作为非线性投影器，即使只有部分观测并且不知道控制方程，也能稳健地捕捉复杂的系统非线性。最后，我们表明，当测量稀疏、不完整且带有噪声，甚至控制方程变得不准确时，我们的网络仍然可以产生相当准确的预测，从而为实际湍流系统的无模型预测铺平了道路。
An access control model called Zero Trust Architecture (ZTA) has attracted attention. ZTA uses information of users and devices, called context, for authentication and authorization. Zero Trust Federation (ZTF) has been proposed as a framework for extending an idea of identity federation to support ZTA. ZTF defines CAP as the entity that collects context and provides it to each organization (Relying Party; RP) that needs context for authorization based on ZTA. To improve the quality of authorization, CAPs need to collect context from various data sources. However, ZTF did not provide a method for collecting context from data sources other than RP. In this research, as a general model for collecting context in ZTF, we propose a method of linking identifiers between the data source and CAP. This method provides a way to collect context from some of such data sources in ZTF. Then, we implemented our method using RADIUS and MDM as data sources and confirmed that their contexts could be collected and used.
