The Age of Information (AoI) has emerged as a novel concept, metric, and tool in the broad area of Information Sciences. AoI is clearly connected to many aspects of Information Theory, Signal Processing, and multiple applications. However, the fundamental nature of this concept has been elusive so far. This project will investigate all three aspects of the AoI, namely its significance as a performance metric, its usefulness as a tool, and, more importantly, its potential to explore profound aspects of, and fundamental interconnections among, the theories that underlie our understanding of information structure, causal information processing, and the context (or semanteme) of information. Especially in the latter, the context of the communication process is emerging as a well-defined and useful extension of the Shannon doctrine of communication. Namely, communication needs not be just reproducing at point B a message selected at point A. Rather, it is important to consider whether communication occurs for a purpose, such as for computation, prediction, or monitoring. Educational efforts will include course development at both undergraduate and graduate levels. The investigators will also strengthen the strong programs of their Institutions in recruiting women and under-represented minorities, as well as the involvement of undergraduate students in research.The proposed work aims at using the new concept of Age of Information to discover the relationships between Information Theory and Signal Processing, which are two of the main pillars of Information Science. Its foundational core is the context of communication, namely on the purposes and goals of signal transmission. This research will be carried out around three thrust areas: (i) the project will explore how the transmission and the age of received updates relate to the information structure of a signal, and understand how information ages over time; (ii) the project will use an innovative approach to the traditional problems of signal processing by relating Nyquist's theory to causal signal reconstruction; (iii) the project will use AoI as a tool in handling the problem of caching and network control in volatile environments (e.g., internet of things and sensor networks).This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

信息时代（AoI）已经成为信息科学广泛领域的一个新概念，度量和工具。AoI显然与信息理论，信号处理和多种应用的许多方面有关。然而，这一概念的基本性质迄今为止一直难以捉摸。该项目将调查AoI的所有三个方面，即它作为性能指标的重要性、它作为工具的有用性，以及更重要的是，它探索理论的深刻方面和基本相互联系的潜力，这些理论是我们理解信息结构、因果信息处理和信息上下文（或语义）的基础。特别是在后者中，沟通过程的背景正在成为香农沟通学说的一个定义明确和有用的扩展。也就是说，通信不需要只是在点B再现在点A选择的消息。相反，重要的是要考虑通信是否出于某种目的而发生，例如计算，预测或监视。教育工作将包括本科和研究生课程的开发。研究人员还将加强其机构在招募女性和代表性不足的少数民族以及本科生参与研究方面的强大计划。拟议的工作旨在使用信息时代的新概念来发现信息理论和信号处理之间的关系，这是信息科学的两个主要支柱。它的基础核心是传播语境，即关于信号传播的目的和目标。该研究将围绕三个重点领域进行：（i）该项目将探索传输和接收更新的年龄如何与信号的信息结构相关，并了解信息如何随着时间的推移而老化;（ii）该项目将通过将奈奎斯特理论与因果信号重建联系起来，使用创新方法来解决信号处理的传统问题;（iii）该计划会使用“服务领域”作为工具，以行程在不稳定的环境（例如，该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
