Dear Anaël, if you wish, you could add a line to the example verifying this correspondence. E.g. by moving the print function from between the two silhouette evaluations to after and also evaluating that average and printing it in parentheses.
Probably not necessary though. A comment would do also. Or nothing :) Michael On Fri, Oct 14, 2016 at 3:38 PM, Raghav R V <rag...@gmail.com> wrote: > On Fri, Oct 14, 2016 at 3:27 PM, Anaël Bonneton <anael.bonne...@gmail.com> > wrote: > >> Hi, >> >> In the silhouette example (http://scikit-learn.org/stabl >> e/auto_examples/cluster/plot_kmeans_silhouette_analysis. >> html#sphx-glr-auto-examples-cluster-plot-kmeans-silhouette-analysis-py), >> the silhouette values of each sample is computed twice: once with >> *silhouette_score >> *and once with *silhouette_samples.* The call to *silhouette_score* can >> be easily avoided by computing the average of the result of* >> silhouette_samples*. >> >> Do you think we should remove the call to *silhouette_score* to improve >> the performance ?
