Unformatted text preview: CHALLENGE 11.4. A sample program is given on the website and results are shown in Figure 11.4. This kMeans function is much faster than the algorithm for Challenge 3. The best results for k = 3 and k = 5 are those from kmeans, but the k = 4 result from minimizing R seems somewhat better than the other k = 4 results. The quantitative measures are mixed: the 2norm of the relative change is .247, .212, and .153 for k = 3 , 4 , 5 respectively, although the algorithm was not run to convergence....
