1. Topic

Select the population of each region and the ratio of male to female in the sixth census of the People's Republic of China for K-Means cluster analysis.

2. Code

# K取值2
print("step2.1:聚类")
k=2
centroids,clusterAssment=kmeans(dataSetKNN1,k)
print('数据类型：',dataSetKNN1.dtype)
print("step3.1:结果输出：见'图11.2.2.png'")
showCluster_2(dataSetKNN1,k,centroids,clusterAssment)

# K取值3
print("step2.2:聚类")
k=3
centroids,clusterAssment=kmeans(dataSetKNN1,k)
print('数据类型：',dataSetKNN1.dtype)
print("step3.2:结果输出：见'图11.2.3.png'")
showCluster_2(dataSetKNN1,k,centroids,clusterAssment)
