(2004) in 2004, as an alternative to standard linkage methods used in hierarchical clustering. Minimax linkage relies on distances to a prototype for each cluster; this prototype can be thought of as a representative object in the cluster, hence improving the interpretability of clustering results....

Hierarchical Clustering是一种基于层次的聚类方法,其基本思想是通过不断合并相邻的簇来形成一个层次结构。(类似于反向生成树) 原理 Hierarchical Clustering的原理是通过计算数据点之间的距离来形成一个距离矩阵,然后通过不断合并最近的两个簇来形成一个层次结构。具体来说,算法的步骤如下: 将每个数据点视为一个簇。

Z = linkage(X)返回一个矩阵Z,该矩阵是将实矩阵X的行编码为一个层次聚类的数。 Z = linkage(X,method)用特定的方法method生成树,方法描述的是描述聚类间距离的方式。 Z = linkage(X,method,metric)表现的是用距离度量metric来计算X行之间的距离的聚类。
