Then, the sample points on the manifold are collected as a data set. Moreover, a novel clustering algorithm, namely Riemannian distance based Fuzzy-c means clustering (RDFCM) algorithm, is developed ...

In order to solve the problem that the traditional fuzzy c-means (FCM) clustering algorithm can not directly act on incomplete data, a modified algorithm IDFCM (Incomplete Data FCM) based on the FCM ...
