不相容决策表中知识约减算法的比较分析
Comparative Analysis of Knowledge Reduction Approaches in Inconsistent Decision Table
摘要
Abstract
The results obtain by using three knowledge reduction approaches (algebra approach,information approach and discernibility-matrix-based approach) respectively may be different in inconsistent decision table.This paper is devoted to generalize those reducts and reveal those reducts' usefulness in case of analyzing inconsistent decision table.Hence,the selection of knowledge reduction approaches can be determined by the request of different levels of decision granularity so as to generate proper decision rules in the model of approximate and uncertain reasoning about knowledge.The conclusions are beneficial in further studies on models and algorithms of data preprocessing to control the degree of the conflicting for decision table.关键词
