The data mining uses various clustering algorithms for grouping related objects. One of the most important clustering algorithm is density based clustering algorithm, which groups the related objects in non linear shapes structure based on the density. But it has the problem of varied density, which...

百度百科中对聚类(Clustering)的释义为:将物理或抽象对象的集合分成由类似的对象组成的多个类的过程被称为聚类。 在机器学习领域中,我们对聚类(Clustering)的理解可以是这样:按照某个特定标准(比如说可以基于距离)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,不在同一个簇中的数据...
Clustering is a form of learning by observations. It is an unsupervised learning method and does not require training data set to generate a model. Clustering can lead to the discovery of previously unknown groups within the data. It is a common method of data mining in which similar and ...
In 2014, the DBSCAN algorithm was awarded the test of time award (an award given to algorithms which have received substantial attention in theory and practice) at the leading data mining conference, ACMSIGKDD. —Wikipedia Introduction Clustering analysis is an unsupervised learning method that separ...
