序区间值决策系统中最优可信规则获取与约简
Acquisition of all credible rules and reductions in ordered interval-valued decision systems
摘要
Abstract
In the ordered decision system, it can induce all of the credible rules based on the descriptors, but which cannot direct support for interval value. To solve this problem, this paper proposed a new concept of segmented interval value based on the range of domain of each condition attributes, then the ordered interval-valued decision system could be changed to an ordered segmented interval-valued decision system. Secondly,based on the segmented interval value,it proposed the concepts of the increasing and decreasing descriptors. Finally,it investigated the reductions and relative reductions in terms of the decision classes of these two new descriptors, and gave the judgment theorems and discernibility functions with respect to these reductions. These methods provide a theory and practical approach, which can generate all compact and effective optimal credible decision rules from the old ordered decision system including interval data.关键词
