PAM-lite: Fast and accurate k-medoids clustering for massive datasets

Author: Olukanmi, PO ; Nelwamondo, Fulufhelo V ; Marwala, T Date: Jan 2019 The 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
Performance evaluation of sampling-based large-scale clustering algorithms

Author: Olukanmi, PO ; Nelwamondo, Fulufhelo V ; Marwala, T Date: Jan 2019 Using 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
