# K-means clustering using Lloyd's algorithm in pure Python. | |
# Written by Lars Buitinck. This code is in the public domain. | |
# | |
# The main program runs the clustering algorithm on a bunch of text documents | |
# specified as command-line arguments. These documents are first converted to | |
# sparse vectors, represented as lists of (index, value) pairs. | |
