AI总结:

提出基于异常检测的数据标注方法,通过特定指标解决无真实基准的模型验证问题,应用于食品包装行业,辅助高速生产过程中的故障分类与自学习系统训练。

摘要:

在本文中,我们提出了一种新方法,利用异常检测来辅助对来自快速运行过程的数据进行标注。其结果是能够对高速到达的数据进行人工分类,以训练机器学习模型。为了规避没有真实基准的问题,我们提出了用于模型选择和结果验证的特定指标。该用例取自食品包装行业,该行业的生产过程受到频繁但短暂的故障影响,导致生产过程中断。快速的生产速率使得机器操作员难以识别故障的来源及其原因。自学习辅助系统可以帮助他们找到问题的根本原因,并协助机器操作员应用持久的解决方案。这些学习系统需要通过数据分析进行训练,以识别反复出现的问题。训练并不容易,因为过程太快,无法通过手动监控来为单个数据点添加特定的分类。

英文摘要:

In this paper we propose a new method to assist in labeling data arriving from fast running processes using anomaly detection. A result is the possibility to manually classify data arriving at a high rates to train machine learning models. To circumvent the problem of not having a real ground truth we propose specific metrics for model selection and validation of the results. The use case is taken from the food packaging industry, where processes are affected by regular but short breakdowns causing interruptions in the production process. Fast production rates make it hard for machine operators to identify the source and thus the cause of the breakdown. Self learning assistance systems can help them finding the root cause of the problem and assist the machine operator in applying lasting solutions. These learning systems need to be trained to identify reoccurring problems using data analytics. Training is not easy as the process is too fast to be manually monitored to add specific classifications on the single data points.
