| 摘 要： | 针对模糊C均值聚类算法不能区分数据各属性之间的不平衡性,提出了一种基于熵权法加权的模糊C均值聚类算法。该算法首先应用熵权法计算各属性的权重系数,然后对标准化之后的原始数据进行加权,最后应用模糊C均值聚类算法对加权之后的数据进行聚类。实验表明,该算法聚类准确率要明显高于未加权的模糊C均值聚类算法。

| Abstract: | For the fuzzy C-means clustering algorithm cannot differentiate the imbalance between the various properties,this paper proposed the fuzzy C-means clustering algorithm based on entropy weight weighted.First,the algorithm applied entropy weight method to calculate the weight coefficient of each attribute;and then,the standardized raw data are weighted;finally fuzzy C-means clustering algorithm was applied to cluster the weighted data.Experiment results showed that the accuracy of this clustering algorithm was significantly higher than unweighted fuzzy C-means clustering algorithm. |
