python - Cutting point in the fastcluster module

Question

I am trying to use Python fastcluster module for hierarchical clustering:

linkage = fastcluster.linkage(distance,method="complete")

It works fine when I know beforehand the number of clusters. But I can not find the syntax for cutting point in the gained hierarchy. I appreciate any help in this direction.

Answer 1

你首先设定了你的标准。根据此标准，您可以选择截止值。例如：

X = np.array([.....])
Y = pdist(X)
Z = linkage(Y)
I = inconsistent(Z)

然后根据一致性结果选择您的截止点。

fcluster(Z,cutoff,criterion='inconsistent')
