AutoML for Multi-Class Anomaly Compensation of Sensor Drift

  • 设计新验证范式,避免训练测试数据重叠导致的性能虚高。
  • 在真实漂移场景下,分类准确率提升超过15%。
  • 适合工业监测中需长期稳定运行的智能系统开发者。

传感器漂移在工业测量系统中严重影响模型精度与可靠性,随时间推移逐渐降低机器学习模型性能。现有模型训练中常用的交叉验证方法因允许数据在训练与测试集间重复出现,高估了模型表现,导致其无法准确预测未来漂移影响,削弱泛化能力。本文提出两种解决方案:(1) 新型传感器漂移补偿验证范式;(2) 基于自动化机器学习(AutoML)的漂移补偿模型(AutoML-DC)。通过数据平衡、元学习、自动集成学习、超参数优化、特征选择与提升等策略,AutoML-DC显著提升了对传感器漂移的分类性能,并有效适应不同漂移强度,显著增强模型在动态环境中的鲁棒性。

原文摘要 · Abstract (English)

Addressing sensor drift is essential in industrial measurement systems, where precise data output is necessary for maintaining accuracy and reliability in monitoring processes, as it progressively degrades the performance of machine learning models over time. Our findings indicate that the standard cross-validation method used in existing model training overestimates performance by inadequately accounting for drift. This is primarily because typical cross-validation techniques allow data instances to appear in both training and testing sets, thereby distorting the accuracy of the predictive evaluation. As a result, these models are unable to precisely predict future drift effects, compromising their ability to generalize and adapt to evolving data conditions. This paper presents two solutions: (1) a novel sensor drift compensation learning paradigm for validating models, and (2) automated machine learning (AutoML) techniques to enhance classification performance and compensate sensor drift. By employing strategies such as data balancing, meta-learning, automated ensemble learning, hyperparameter optimization, feature selection, and boosting, our AutoML-DC (Drift Compensation) model significantly improves classification performance against sensor drift. AutoML-DC further adapts effectively to varying drift severities.
