Abstract：The decision function of density peak clustering algorithm cannot determine the clustering center automatically and effectively. Therefore, a density peak clustering algorithm, automatically clustering by fast search and find of density peaks(AUTO-CFSFDP), is proposed. Firstly, the normalization process is carried out to make the uneven distribution of variables in the decision function become uniform. Secondly, the selection strategy based on positive-sequence iteration is presented to search elbow point according to the variation trend of the number of cluster core points in the process of determining the cluster center. A set of points before the elbow point is used as the cluster centers to complete clustering. Finally, the performance of AUTO-CFSFDP is evaluated on UCI datasets. AUTO-CFSFDP can cluster the datasets of arbitrary distributions without extra time consumption. The adaptability and clustering results are improved effectively.
