基于规则的分类系统的质量评价

On Evaluating the Quality of Rule-Based Classification Systems

Mahidol University International College(玛希隆大学国际学院)

Nassim Dehouche

摘要:

两个指标通常用于评估基于规则的分类系统的质量:预测准确性,即系统成功复制学习数据的能力和覆盖率,即构成系统的逻辑规则适用的可能情况的比例。在这项工作中,我们认为这两个指标可能是不够的,可能需要制定额外的质量措施。我们从理论上表明,分类系统呈现“良好”的预测精度和覆盖率,但是,可以微不足道的改进,并举例说明这一命题。

英文摘要:

Two indicators are classically used to evaluate the quality of rule-based classification systems: predictive accuracy, i.e. the system's ability to successfully reproduce learning data and coverage, i.e. the proportion of possible cases for which the logical rules constituting the system apply. In this work, we claim that these two indicators may be insufficient, and additional measures of quality may need to be developed. We theoretically show that classification systems presenting "good" predictive accuracy and coverage can, nonetheless, be trivially improved and illustrate this proposition with examples.
