Author:Olukanmi, P; Nelwamondo, Fulufhelo V; Marwala, TDate:Aug 2020This paper introduces a hybridization of the k-means and k-medoids paradigms. The new algorithms is named HP (hybrid partitioning) algorithm. Specifically, we improve on a recently developed scalable version of k-means (k-means-lite), by ...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
