摘要
针对给案例推理中特征项赋权的两类方法的缺陷及直接组合权重时的不足,本文提出了一种调整组合权重的方法,该方法先将主观赋权的值经熵值法调整,同客观赋权的值组合建立数学模型,用遗传算法求其最优解,得到人为因素影响最小的组合权值。实验结果表明,调整的组合权重更有利于实例检索。
This paper presents a method of combined weight because of the defects of two kinds of setting weight methods and the shortcoming of directly combined weight in CBR, Using the Entropy to adjust subjective weight firstly in this method, then combined with objective weight for mathematical model ,GA is used for finding the best combined weights with the smallest human factors. The experiment result shows that the method has a good performance in finding the right cases.
