【摘要】 通过定义单边三角形模糊数空间上的一种全序关系,提出了属性取值为单边三角形模糊数的决策树学习算法.作为ID3算法在单边三角形模糊数意义下的推广,算法通过一种分割信息熵的极小化来选取扩展属性.通过非平稳割点的分析,减少了分割信息的计算次数,使算法的效率得到了提高.更多还原

【Abstract】 The paper defines a total order on one-side triangular fuzzy numbers,then presents rules of learning algorithm,that is,one-side decision trees or rules using the information entropy minimization heuristic.The result serves to give a better understanding of the entropy measure,to point out that the behavior of the information entropy heuristic is desirable,and to improve the efficiency of evaluating attributes,for cutting value selection.更多还原
