A New Clustering Algorithm Based on Ward_PAM

Hongmei Nie
Abstract—Ward algorithm is one of the system clustering methods. The algorithm makes two large classes easily generate a large distance so as to be not easy to be merged, in contrast, it makes two small classes generate a small distance and be easy to be merged. However, the limitation of the method is that it is difficult for the class that has been obtained to be classified again. If we first use Ward method clustering samples, then make each of the obtained classes use PAM algorithm, so that each class can have a chance to be redivided, so get a more detailed clustering effect. In view of this idea, the paper proposes a new clustering method based on Ward and PAM (Ward & PAM algorithm). The proposed method combines the advantages of the two algorithms, which makes the clustering result be more accurate and detailed. Moreover, the paper optimizes the algorithm index formula. Finally, this paper makes a detailed comparison analysis of the experimental results. The experimental result analysis shows that the performance of Ward & PAM algorithm is better than that of Ward algorithm.

Index Terms—Ward algorithm, PAM algorithm, clustering, validity index.
