首发时间:2011-02-25
摘要:为从决策表中获取最简决策规则,在定义粒矩阵和矩阵运算的基础上,提出了一种基于二进制粒矩阵的决策规则提取算法。该算法从粒库中尽可能多地提取出具有一定规则确定度与覆盖度的简洁规则,且能更充分地挖掘决策表中的知识,最后用实例验证了其可行性。

Extraction Rules Based on Bit Granular Matrix
Abstract:To extract compact decision rules from decision table,based on the definition of bit granular matrix (BGrM),a matrix-based decision rules extraction algorithm is proposed. The algorithm about the briefest rule acquisition is presented with which satisfy degree of certainty and coverage of rules using the methods of granular computing as many as possible. The correctness and effectiveness of the new algorithm are shown in an example.
Keywords: granular computing BGrM(bit granular matrix) extraction rules
