| 摘 要： | 针对区间直觉模糊集(IVIFS)的聚类问题,提出了基于IVIFS的C均值聚类算法.算法首先应用IVIFS的欧氏距离,构造了聚类的目标函数;然后根据拉格朗日乘数法推导出聚类的迭代公式,得到IVIFS聚类算法;此外,还提出一种IVIFS聚类的有效性函数,并将此函数和聚类结合,给出可以确定最佳聚类类别数的聚类流程;最后通过实...

| Abstract: | Aiming at the clustering problems of IVIFS,the C-means clustering algorithm based on IVIFS is proposed.By means of the Euclidian distance,the objective function of clustering is constructed.Next the iterative formula is deduced according to Lagrange multiplier method,then IVIFS clustering algorithm is obtained.Moreover an IVIFS clustering validity function is defined to confirm the best clustering class number's clustering procedure.Finally,experiment results show that the method can not only acquire the be... |
