论文摘要
在现代业务流程中,近年来收集的数据数量大大增加。由于这些数据可能会产生有价值的见解,因此除其他技术外,还提出了基于过程挖掘的自动知识提取,以使用户可以直观地访问其中包含的信息。目前,大多数技术旨在重建明确的业务流程模型。这些是可以直接解释的,但是关于多样化和实现的信息源的整合的限制。另一方面,机器学习(ML)受益于可用的大量数据,并且可以处理高维源,但很少将其应用于流程中。在这项贡献中,我们评估了现代变压器架构的能力以及建模过程规律性的更古典的ML技术,可以通过其预测能力进行定量评估。此外,我们通过强调对过程的预测能力至关重要的特征来证明注意力特性的能力和特征相关性确定。我们使用五个基准数据集证明了方法的功效,并表明ML模型能够预测关键结果,并且注意机制或XAI组件为基础过程提供了新的见解。
In modern business processes, the amount of data collected has increased substantially in recent years. Because this data can potentially yield valuable insights, automated knowledge extraction based on process mining has been proposed, among other techniques, to provide users with intuitive access to the information contained therein. At present, the majority of technologies aim to reconstruct explicit business process models. These are directly interpretable but limited concerning the integration of diverse and real-valued information sources. On the other hand, Machine Learning (ML) benefits from the vast amount of data available and can deal with high-dimensional sources, yet it has rarely been applied to being used in processes. In this contribution, we evaluate the capability of modern Transformer architectures as well as more classical ML technologies of modeling process regularities, as can be quantitatively evaluated by their prediction capability. In addition, we demonstrate the capability of attentional properties and feature relevance determination by highlighting features that are crucial to the processes' predictive abilities. We demonstrate the efficacy of our approach using five benchmark datasets and show that the ML models are capable of predicting critical outcomes and that the attention mechanisms or XAI components offer new insights into the underlying processes.
