Author:Olukanmi, PO; Nelwamondo, Fulufhelo V; Marwala, TDate:Jan 2019The Partitioning Around Medoids (PAM) clustering algorithm is well-known for its robustness and accuracy, but it is computationally expensive. This paper proposes a fast and accurate version, named PAM-lite. Like CLARA which also addresses ...Read more
Author:Olukanmi, PO; Nelwamondo, Fulufhelo V; Marwala, TDate:Jan 2019Using benchmark datasets, we study the performances of three efficient clustering algorithms which find cluster centers using a fixed number of random samples. The algorithms are also compared with two other (well-known) algorithms, namely ...Read more
