基于核密度峰值聚类和细粒度噪声抑制的特征选择方法OA
Feature Selection Method Based on Kernel Density Peak Clustering and Fine-Grained Noise Suppression
针对传统特征选择方法易受噪声影响以及所获得的特征空间易导致数据分布改变的问题,文中提出了一种基于核密度峰值聚类和细粒度噪声抑制特征选择(Feature Selection based on Fine-Grained Noise Suppression and Kernel Density Peak Clustering,FNKC)方法.为了克服噪声对特征选择影响,利用可能性模糊 C 均值算法(Possibilistic Fuzzy C-means Clustering Algorithm,PFCM)的可能性定理并结合信息粒准则来提取数据相关性,提高了抗噪性能.文中还在高维空间引入核密度来测量聚类密度,精确捕捉了簇内空间结构,从而更好地反映数据的分布.最后,通过在 6 个公共高维数据集对比多个先进的特征选择方法验证了所提算法的优越性和有效性.
In view of the problems that traditional feature selection methods are vulnerable to noise and the ob-tained feature space is prone to cause changes in data distribution,this study proposes a FNKC(Feature Selection based on Fine-Grained Noise Suppression and Kernel Density Peak Clustering).To overcome the influence of noise on feature selection,the possibility theorem of the PFCM(Possibilistic Fuzzy C-means Clustering Algorithm)is uti-lized in combination with the information particle criterion to extract data correlation,thereby improving the anti-noise performance.Introducing kernel density in high-dimensional space to measure clustering density can accurately cap-ture the spatial structure within clusters,thereby better reflecting the distribution of data.Finally,the superiority and effectiveness of the proposed algorithm are verified by comparing multiple advanced feature selection methods on six public high-dimensional datasets.
