- Abstract:
-
Clustering is a fundamental issue for big data analysis and data mining. In July 2014, a paper in the Journal of Science proposed a simple yet effective clustering algorithm based on the idea that cluster centers are characterized by a higher density than their neighbors and having a relatively large distance from points with higher densities. The proposed algorithm can detect clusters of arbitrary shapes and differing densities but is very sensitive to tunable parameter dc. In this paper, we propose an improved clustering algorithm that adaptively optimizes parameter dc. The time complexity of our algorithm was super-linear with respect to the size of the dataset. Further, our theoretical analysis and experimental results show the effectiveness and efficiency of our improved algorithm.
