摘要:

粒子加速器是一种复杂的设备,它产生大量结构化数据,并具有明确的优化目标以及精确定义的控制要求。因此,它们自然适合数据驱动的研究方法。来自加速器内部的传感器和监视器的数据形成多变量时间序列。随着快速抢占式方法在加速器控制和诊断中的高度优先选择,数据驱动的时间序列预测方法的应用特别有前途。本文综述了时间序列预测问题,并总结了现有的模型在各个科学领域的应用。介绍了粒子加速器领域目前和未来的几种尝试。时间序列预测在粒子加速器中的应用已经显示出令人鼓舞的结果和更广泛应用的前景,并且已经开始解决诸如数据一致性和兼容性之类的现有问题。

英文摘要:

Particle accelerators are complex facilities that produce large amounts of structured data and have clear optimization goals as well as precisely defined control requirements. As such they are naturally amenable to data-driven research methodologies. The data from sensors and monitors inside the accelerator form multivariate time series. With fast pre-emptive approaches being highly preferred in accelerator control and diagnostics, the application of data-driven time series forecasting methods is particularly promising. This review formulates the time series forecasting problem and summarizes existing models with applications in various scientific areas. Several current and future attempts in the field of particle accelerators are introduced. The application of time series forecasting to particle accelerators has shown encouraging results and the promise for broader use, and existing problems such as data consistency and compatibility have started to be addressed.
