Question

我的Python程序：

#!/usr/bin/python
from pylab            import plot,show
from numpy            import vstack,array
from numpy.random     import rand
from scipy.cluster.vq import kmeans, vq, whiten

import csv

if __name__ == "__main__":

    K = 3

    data_arr = []

    clust_name_arr = []

    with open('clustering.csv', 'rb') as f:

        reader = csv.reader(f)

        for row in reader:

            data_arr.append([float(x) for x in row[1:]])

            clust_name_arr.append([row[0]])

    data = vstack( data_arr )

    clust_name = vstack(clust_name_arr)

   data = whiten(data)



    centroids, distortion = kmeans(data,3)

    print "distortion = " + str(distortion)



    idx,_ = vq(data,centroids)



    plot(data[idx==0,0], data[idx==0,1],'ob',

         data[idx==1,0], data[idx==1,1],'or',

         data[idx==2,0], data[idx==2,1],'og')

    print clust_name

    print data

    for i in range(K):

        result_names = clust_name[idx==i, 0]

        print "================================="

        print "Cluster " + str(i+1)

        for name in result_names:

            print name

    plot(centroids[:,0],

         centroids[:,1],

         'sg',markersize=8)

    show()
