摘要:

从给定数据集中检测相关模式集是数据采掘中的一个重要挑战。模式的相关性,在文献中也称为效用,是一种主观的衡量标准,实际上可以从非常不同的角度进行评估。基于规则的语言,如答案集编程(ASP)似乎非常适合指定用户提供的标准,以评估模式效用的约束形式;此外,ASP的声明性允许在几个标准之间进行非常容易的切换,以便从不同的角度分析数据集。在本文中,我们采取步骤扩展的概念高效用模式挖掘(HUPM),特别是我们引入了一个新的框架,允许新的类的效用标准没有考虑在以前的文献。我们还展示了如何最近扩展的ASP与外部功能可以支持一个快速有效的编码和测试的新框架。为了证明所提出的框架的潜力,我们将其作为构建模块,用于定义预测COVID-19患者入住ICU的创新方法。最后,一个广泛的实验活动从定量和定性的角度证明了所提出的方法的有效性。逻辑程序设计理论与实践(Theory and Practice of Logic Programming,TPLP)

英文摘要:

Detecting sets of relevant patterns from a given dataset is an important challenge in data mining. The relevance of a pattern, also called utility in the literature, is a subjective measure and can be actually assessed from very different points of view. Rule-based languages like Answer Set Programming (ASP) seem well suited for specifying user-provided criteria to assess pattern utility in a form of constraints; moreover, declarativity of ASP allows for a very easy switch between several criteria in order to analyze the dataset from different points of view. In this paper, we make steps toward extending the notion of High Utility Pattern Mining (HUPM); in particular we introduce a new framework that allows for new classes of utility criteria not considered in the previous literature. We also show how recent extensions of ASP with external functions can support a fast and effective encoding and testing of the new framework. To demonstrate the potential of the proposed framework, we exploit it as a building block for the definition of an innovative method for predicting ICU admission for COVID-19 patients. Finally, an extensive experimental activity demonstrates both from a quantitative and a qualitative point of view the effectiveness of the proposed approach.
