基于自适应近邻信息的模糊C均值聚类算法OA北大核心CSTPCD

Traditional FCM algorithms cluster based on raw data,risking distortion from noise,outliers,or other disruptions,which can degrade clustering outcomes.To bolster FCM's resilience,this study intro-duces a fuzzy C-means clustering algorithm that leverages adaptive neighbor information.This concept hinges on the similarity between data points,treating each point as a potential neighbor to others,albeit with varying degrees of similarity.By integrating the neighbor information of sample points,labeled GX,and that of cluster centers,labeled GV,into the standard FCM framework,the algorithm gains additional insights into data structure.This aids in steering the clustering process and enhances the algorithm's robust-ness.Three iterative methods are presented to implement this enhanced clustering model.When com-pared to leading clustering techniques,our approach demonstrates over a 10%improvement in cluster-ing efficacy on select benchmark datasets.It undergoes thorough evaluation across different dimen-sions,including parameter sensitivity,convergence rate,and through ablation studies,confirming its practicality and efficiency.
