High-rate systems are defined as dynamic systems experiencing high-rate and high-amplitude events. Examples include hypersonic vehicles and active impact mitigation strategies. The advanced operation of these mechanisms can only be achieved through control and feedback systems capable of operating in the sub-millisecond range, thus necessitating tight performance constraints. Additionally, high-rate systems are highly nonlinear and nonstationary, for which traditional real-time inference methods are incapable of providing credible predictions. Topological data analysis is gaining popularity for classifying complex time series. Its integration with architected machine learning algorithms shows promise in advancing the predictive capabilities for high-rate systems. However, topological data analysis is computationally expensive and cannot be applied in the sub-millisecond range. This project will investigate real-time topological data analysis capabilities by developing and integrating advances in mathematical, software, and hardware foundations. Successful completion of this project will yield theoretical foundations enabling the integration of topological data analysis with machine learning for modeling and forecasting time series, constituting a major leap from the pure algebraic topological approach. It is envisioned that the developed foundations, along with software and hardware artifacts, will find applications in supercomputing, high-speed data storage, connected vehicles, financial fraud mitigation, cyber-security, deep-fake detection, active blast shielding, and hypersonic vehicles. This project will broaden participation in computing by training multiple undergraduate and graduate students through a well-structured research and education plan that leverages existing programs and partnerships at the three partnering universities, including an undergraduate historically black college.This project will demonstrate that complex nonstationary systems can be learned in real-time by integrating modern mathematical tools combined with advances in hardware, notably by generating a field-programmable gate array design for a real-time predictor running on the edge. To that end, customized variations of traditional topological data analysis will be developed to meet the needs of the targeted modeling and forecasting tasks while producing computationally efficient machine learning representations. Concurrently, opportunities and limitations in conducting topological data analysis in real-time and in producing a modular automated programmer for heterogeneous hardware will be identified. Then, software and hardware discoveries will be integrated to demonstrate real-time topological data analysis and to conduct time series modeling and forecasting. Undergraduate students involved in these research projects will be provided with long-term mentored research and learning experiences.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.

高速率系统被定义为经历高速率和高幅度事件的动态系统。例子包括高超音速飞行器和主动影响缓解策略。这些机制的高级操作只能通过能够在亚毫秒范围内运行的控制和反馈系统来实现，因此需要严格的性能限制。此外，高速系统具有高度非线性和非平稳性，传统的实时推理方法无法提供可靠的预测。拓扑数据分析在对复杂时间序列进行分类方面越来越受欢迎。它与结构化机器学习算法的集成显示出在提高高速系统的预测能力方面的前景。然而，拓扑数据分析的计算成本很高，并且不能在亚毫秒范围内应用。该项目将通过开发和集成数学、软件和硬件基础的进步来研究实时拓扑数据分析能力。该项目的成功完成将为将拓扑数据分析与机器学习相结合以建模和预测时间序列奠定理论基础，这是纯代数拓扑方法的重大飞跃。预计所开发的基础以及软件和硬件工件将在超级计算、高速数据存储、联网车辆、金融欺诈缓解、网络安全、深度伪造检测、主动爆炸屏蔽和高超音速飞行器等领域得到应用。该项目将通过一个结构良好的研究和教育计划来培训多名本科生和研究生，从而扩大对计算的参与，该计划利用三所合作大学的现有项目和合作伙伴关系，其中包括一所本科生历史悠久的黑人学院。该项目将证明复杂的非平稳系统可以通过将现代数学工具与硬件进步相结合来实时学习，特别是通过为在边缘运行的实时预测器生成现场可编程门阵列设计。为此，将开发传统拓扑数据分析的定制变体，以满足目标建模和预测任务的需求，同时产生计算高效的机器学习表示。同时，将确定实时进行拓扑数据分析和为异构硬件生成模块化自动化编程器的机会和限制。然后，将集成软件和硬件发现来演示实时拓扑数据分析并进行时间序列建模和预测。参与这些研究项目的本科生将获得长期指导的研究和学习经验。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
