This article would like to introduce to youhierarchical clustering, first introduce its basic theory through a simple example, and then use a practical casePythoncode to achieve the clustering effect. First of all, clustering belongs to unsupervised learning of machine learning, and there are many ...

(3) Birch Birch是平衡迭代归约及聚类算法,全称为Balanced Iterative Reducing and Clustering using Hierarchies,是一种常用的层次聚类算法。该算法通过聚类特征(Clustering Feature,CF)和聚类特征树(Clustering Feature Tree,CFT)两个概念描述聚类。聚类特征树用来概括聚类的有用信息,由于其占用空间小并且可以存放在内存中...
ClusteringQuality类测量给定输入模式的聚类的质量。 聚类理论 - 聚类中的蒙特卡罗方法 K-Means聚类算法的两个最大问题是: 它对质心的随机初始化很敏感 初始化的质心数,k 由于这些原因,K-means聚类算法经常重启多次。因为初始化(通常)是随机的,所以我们基本上对质心的随机高维起始位置进行采样,这也称为蒙特卡罗模拟。
