The components of data clustering are the steps needed to perform a clustering task. Different taxonomies have been used in the classification of data clustering algorithms Some words commonly used are approaches, methods or techniques (Jain et al.1999; Liao2005; Bulò and Pelillo2017; Govender an...

Data Clustering - Detecting Abnormal Data Using k-Means Clustering By James McCaffrey Consider the problem of identifying abnormal data items in a very large data set, for example, identifying potentially fraudulent credit-card transactions, risky loan applications and so on. One approach to detecting...

Clustering ,翻译为"聚类",就是把相似的东西分为一组,同 Classification(分类)不同, classifier 从训练集中进行"学习",从而能够对未知数据进行分类,这种提供训练数据的过程叫做 supervised learning (监督学习),而在聚类的时候,我们并不关心某一类是什么,我们只需要把相似的东西聚到一起,因此,一个聚类算法通常只需要...
