摘要: 伴随着数字化转型和智能技术的高速发展,工业制造、金融交易与能源管理等领域愈发依赖大量的时序数据来支撑关键决策。异常事件的突发性不仅会对系统性能构成威胁,也严重影响整体安全性,因此如何高效地从大规模且结构复杂的数据中识别异常成为当前亟待解决的挑战。聚焦于时序异常检测问题,探讨工业数据集噪声存在对模型训练的干扰,并提出了一种改进策略。工业环境中采集的数据往往具有高维、多噪声等特点,当训练样本中混入噪声时,模型的学习过程易受扰动,导致鲁棒性降低。以往研究主要采用单一指标对噪声样本进行识别和过滤,这种方法在训练过程中可能引入累积误差,进而影响异常检测的准确性。为应对上述问题,提出了一种基于多视角交叉过滤的鲁棒时序异常检测模型(Robust Time Series Anomaly Detection Model Based on Multi-View Cross Filtering,MVCF-AD),该模型首先引入非邻域注意力概念,并结合重构误差构造了用于噪声判别的双指标体系。随后,通过构建多视角交叉过滤策略,并采用并行训练双网络的方式,利用损失排序实现对噪声样本进行动态识别与过滤。实验结果显示,MVCF-AD在不同噪声率下均表现出卓越的检测性能和鲁棒性,证明了该方法在应对数据集噪声问题上的有效性。
