这里，我们来解读一下scipy中给出的层次聚类scipy.cluster.hierarchy的示例： import numpy as np
from scipy.cluster.hierarchy import dendrogram, linkage,fcluster
from matplotlib import pyplot as plt
X = [[i] for i in [2, 8, 0, 4, 1, 9, 9, 0]]...
获取数组中的部分元素除了通过指定索引标签来实现外，还可以通过使用一些函数来实现，如通过random.choice函数从指定的样本中随机抽取数据。 import numpy as np
from numpy import random as nr
a=np.arange(1,25,dtype=float)
c1=nr.choice(a,siz...
