摘要:

本文介绍了重描述模型挖掘,一种新的方法来识别跨两个数据集,只有一个子集的属性共享,没有共同的实例可解释的模式。特别是,重描述模型挖掘的目的是找到成对的可描述的数据子集-每个数据集一个-诱导类似的特殊模型相对于一个预先指定的模型类。为了实现这一目标,我们结合了两个以前独立的研究领域:异常模型挖掘和重描述挖掘。对于这个新的问题设置,我们开发了兴趣度度量来选择有希望的模式,提出有效的算法,并在合成和真实世界数据上展示它们的潜力。未覆盖的模式可以暗示跨数据集表现出来的常见潜在现象,从而能够发现未出现在同一数据集中的属性(组合)之间的可能关联。

英文摘要:

This paper introduces Redescription Model Mining, a novel approach to identify interpretable patterns across two datasets that share only a subset of attributes and have no common instances. In particular, Redescription Model Mining aims to find pairs of describable data subsets -- one for each dataset -- that induce similar exceptional models with respect to a prespecified model class. To achieve this, we combine two previously separate research areas: Exceptional Model Mining and Redescription Mining. For this new problem setting, we develop interestingness measures to select promising patterns, propose efficient algorithms, and demonstrate their potential on synthetic and real-world data. Uncovered patterns can hint at common underlying phenomena that manifest themselves across datasets, enabling the discovery of possible associations between (combinations of) attributes that do not appear in the same dataset.
