摘要: 将泛化分配表(GDT)作为假说搜索空间, 提出了一种从不一致和不完全的数据中提取缺省规则的算法. 使用该算法可以从不一致和不完全的数据中挖掘缺省规则, 同时该算法可过滤数据中的噪声, 并且可以对未见实例进行预测.

关键词: 泛化分配表, 缺省规则, 不一致性, 不完全性

Abstract: By using a generalization distribution table (GDT) as a hypothesis search space, this paper presents an algorithm to discover default rules from the information system with inconsistencies and incompleteness, by which the default rule can be mined and the noisy in the data can be filtered, and unseen instances can be predicted.

Key words: generalization distribution table, default rules, inc onsistency, incompleteness
