数据质量监控(DQM)是粒子物理实验的关键环节,确保记录数据满足后续物理分析要求。由于极端环境、海量数据及探测器规模与复杂性,传统DQM协调极为困难。因此,利用机器学习(ML)实现异常检测、提升效率并减少人为错误已成为必然趋势。由于DQM依赖真实实验数据,其方法与具体探测器结构和运行技术密切相关。本文提出一种仿真驱动的DQM方法,可在受控环境中研究与开发数据质量评估技术。基于改进版Delphes(一款快速多用途探测器模拟工具),我们实现了初步框架,利用ML识别探测器异常并定位故障组件。本文引入MEDIC(Event Data Integrity and Consistency Monitoring),一个旨在学习探测器行为并执行DQM任务的神经网络。尽管当前实现采用简化设置(故意关闭大区域以模拟故障),但结果令人鼓舞,证明了仿真驱动研究在构建未来更先进、数据驱动的DQM系统中的基础价值。
原文摘要 · Abstract (English)
Data Quality Monitoring (DQM) is a crucial component of particle physics experiments and ensures that the recorded data is of the highest quality, and suitable for subsequent physics analysis. Due to the extreme environmental conditions, unprecedented data volumes, and the sheer scale and complexity of the detectors, DQM orchestration has become a very challenging task. Therefore, the use of Machine Learning (ML) to automate anomaly detection, improve efficiency, and reduce human error in the process of collecting high-quality data is unavoidable. Since DQM relies on real experimental data, it is inherently tied to the specific detector substructure and technology in operation. In this work, a simulation-driven approach to DQM is proposed, enabling the study and development of data-quality methodologies in a controlled environment. Using a modified version of Delphes -- a fast, multi-purpose detector simulation -- the preliminary realization of a framework is demonstrated which leverages ML to identify detector anomalies as well as localize the malfunctioning components responsible. We introduce MEDIC (Monitoring for Event Data Integrity and Consistency), a neural network designed to learn detector behavior and perform DQM tasks to look for potential faults. Although the present implementation adopts a simplified setup for computational ease, where large detector regions are deliberately deactivated to mimic faults, this work represents an initial step toward a comprehensive ML-based DQM framework. The encouraging results underline the potential of simulation-driven studies as a foundation for developing more advanced, data-driven DQM systems for future particle detectors.
