One such algorithm for the GPU is CUDA-DClust. In this paper, we propose a new GPU-accelerated DBSCAN algorithm with several optimizations. In comparison to prior work, our algorithm, CUDA-DClust+: (i) computes the indexing structure on the GPU, (ii) uses kernel fusion to combine the ...
1、DBSCAN简介 DBSCAN(Density-Based Spatial Clustering of Applications with Noise,具有噪声的基于密度的聚类方法)是一种基于密度的空间聚类算法。该算法将具有足够密度的区域划分为簇,并在具有噪声的空间数据库中发现任意形状的簇,它将簇定义为密度相连的点的最大集合。 该算法利用基于密度的聚类的概念,即要求聚类空...

另一种著名的基于密度的聚类方法称为光学算法,它改进了 DBSCAN ,并使用分层聚类来发现密度不同的聚类。光学技术通过将点投影到一个新的空间(称为可达空间)来改进标准的单链接聚类,该空间将噪声从密集区域进一步移开,使其更易于处理。然而,与许多其他层次聚集聚类方法(如单链接聚类和完全链接聚类)一样, OPTICS 也...

聚类(Clustering)是按照某个特定标准(如距离)把一个数据集分割成不同的类或簇,使得同一个簇内的数据对象的相似性尽可能大,同时不在同一个簇中的数据对象的差异性也尽可能地大。也即聚类后同一类的数据尽可能聚集到一起,不同类数据尽量分离。 主要的聚类算法可以划分为如下几类:划分方法、层次方法、基于密度的...
