    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (499 KB) | HTML iconHTML

    As a density based clustering algorithm, DBSCAN plays an important role in data mining. Normally DBSCAN algorithm is computationally expensive, limiting its performance in large-scale data sets, especially in high dimensional data sets. The high complexity is rooted from the region queries, a very common operation in density based algorithms, which brings the complexity of the algorithms to O(n View full abstract»
