Abstract: Kernel PCA method extracts feature from large samples and high dimension data sets,combining CA to select optimized kernel function or near optimized kernel function.FCM based on the method not only effectively extracts the nonlinear information from the samples but also reduces dimension.Experiment shows its better clustering result and less train time.

Key words: kernel principle component analysis, cultural algorithm, fuzzy clustering

摘要: 利用核函数主元分析(KPCA)方法对大样本、高维数据进行特征提取预处理,并结合文化算法(CA)选择最优或接近最优的核函数,将其用于模糊C均值(FCM)聚类中,不但有效地提取了样本的非线性信息,而且使样本维数得到约简。实验表明该方法具有较好的聚类效果和更少的训练时间。
