摘要:

约束条件下的序列模式挖掘是一个具有挑战性的数据采掘任务。许多有效的ad hoc方法已经被开发用于挖掘序列模式,但它们都缺乏通用性。最近的工作已经调查了约束编程(CP)的方法,但他们仍然是有效的,因为他们的编码。在本文中,我们提出了一个全球性的约束的基础上投影数据库的原则,弥补了这一缺陷。实验表明,我们的方法明显优于CP方法,并在大型数据集上与ad hoc方法竞争。

英文摘要:

Sequential pattern mining under constraints is a challenging data mining task. Many efficient ad hoc methods have been developed for mining sequential patterns, but they are all suffering from a lack of genericity. Recent works have investigated Constraint Programming (CP) methods, but they are not still effective because of their encoding. In this paper, we propose a global constraint based on the projected databases principle which remedies to this drawback. Experiments show that our approach clearly outperforms CP approaches and competes well with ad hoc methods on large datasets.
