特征加权距离的半监督模糊子空间聚类算法

Semi-supervised Fuzzy Subspace Clustering Algorithm Based on Feature Weighted Distance

针对已有的基于特征加权距离的双指数模糊子空间聚类算法(DI-FSC)没有充分利用数据集中的已知信息,提出利用少量监督信息辅助聚类过程的特征加权距离的半监督模糊子空间聚类算法(SS-FSC).通过在该算法中加入特征加权距离来改善传统聚类中利用欧氏距离计算数据点之间差异的不足;同时向约束条件中引入指数r和β,增加了算法的灵活性.实验表明,所提出的算法在少量监督信息的辅助下,在真实数据集上有较好的聚类效果.

In view of the existing double-indices fuzzy subspace clustering algorithm based on feature weighted distance （ DI-FSC ） doesn＇t make full use of the known information of the datasets ,put forward a new kind of clustering method using a small amount of supervision information to assist the process of clustering. By introducing the feature weighted distance to improve the disadvantage of using the Euclidean metric to compute the distance between data points. At the same time,adding the index andto the constraint condi- tions to increase the flexibility of the algorithm. Experimental results show that the proposed algorithm under little supervision information on real datasets has better clustering effect.
