1、层次聚类(Hierarchical clustering)的步骤 假设有N个待聚类的样本,对于层次聚类来说,其步骤为: (1)初始化:把每个样本各自归为一类(每个样本自成一类),计算每两个类之间的距离,在这里也就是样本与样本之间的相似度(本质还是计算类与类之间的距离)。 (2)寻找各个类之间最近的两个类,把它们归为一类(这样,类...
In the world of data exploration, where datasets can feel like endless forests, hierarchical clustering is like a guiding light, helping us navigate the complexity. Imagine a dendrogram—a tree-like diagram—that shows how data points are connected and grouped. It’s where machine learning meets...
