摘要:

生成模型是一种统计模型,能够从先前观察到的数据实例生成新的数据实例。在业务流程的上下文中,生成模型从一组历史跟踪(也称为事件日志)创建新的执行跟踪。在以前的工作中已经开发了两个系列的生成过程仿真模型:数据驱动的仿真模型和深度学习模型。到目前为止,这两种方法都是独立发展的,它们的相对性能尚未得到研究。本文通过经验比较数据驱动的模拟技术与多种深度学习技术填补了这一空白,这些技术构建的模型能够生成带有时间戳事件的执行跟踪。这项研究揭示了这两种方法的相对优势,并提出了开发结合这些优势的混合方法的前景。

英文摘要:

A generative model is a statistical model that is able to generate new data instances from previously observed ones. In the context of business processes, a generative model creates new execution traces from a set of historical traces, also known as an event log. Two families of generative process simulation models have been developed in previous work: data-driven simulation models and deep learning models. Until now, these two approaches have evolved independently and their relative performance has not been studied. This paper fills this gap by empirically comparing a data-driven simulation technique with multiple deep learning techniques, which construct models are capable of generating execution traces with timestamped events. The study sheds light into the relative strengths of both approaches and raises the prospect of developing hybrid approaches that combine these strengths.
