Because no training data or user intervention is required, clustering is sometimes termed “unsupervised learning.” Each index in the clustering array represents a tuple and the value in the array is a cluster ID. So tuple 2 (“Suburban,”“VeryHigh,”“Conservative”) is as...
K-Means Clustering, 树状图作为结果有些缺点,第一是计算量巨大,每一级都需要两两计算距离,第二是最后的树状结果并没有把所有的数据放进独立的群组中,还需要额外的工作来完成这一步。所以引入了K-Means 聚类,他与分级聚类的一大区别是我们需要预先告知算法我们要多少个群组,然后算法来计算每个群组的体量。具体的操...
There are many different clustering algorithms. One of the oldest and most widely used is the k-means algorithm. In this article I’ll explain how the k-means algorithm works and present a complete C# demo program. There are many existing standalone data-clustering tools, so why would you ...

The major challenges and future trends of data clustering will also be introduced in this chapter. The remainder of this chapter is organized as follows. The background of data clustering will be introduced in Section 2, including the definition of clustering, categories of clustering techniques, ...
Data clusteringconsists of data mining methods for identifying groups of similar objects in a multivariate data sets collected from fields such as marketing, bio-medical and geo-spatial. Similarity between observations (or individuals) is defined using some inter-observation distance measures including Eu...
