This study proposes a novel Intuitionistic fuzzy c-least squares support vector regression (IFCLSSVR) with sammon mapping clustering algorithm. The proposed clustering algorithm can obtain the advantages of intuitionistic fuzzy sets, LSSVR, and sammon mapping in actual clustering problems. Moreover, IFC-LSSVR with sammon mapping adopts particle swarm optimization (PSO) to search optimal parameters. Experiments on web-based adaptive learning environments data set, which is to provide enough or suitable knowledge for students/users, show that the proposed IFC-LSSVR with sammon mapping is more efficient than conventional algorithms such as the k-means (KM) and fuzzy c-means (FCM) clustering algorithm, in standard measurement indexes.
