That's a great speedup. Is there any noticable deterioration in output
quality?

Subject: [Klustakwik-develop] Newest feature addition to the KlustaKwik
engine


Everyone using KlustaKwik for clustering large datasets will enjoy the 
new k-means preprocessing step.  The new k-means preprocessing step gave 
an approximately 5x improvement in processing throughput.  A dataset 
which took 60m6s without k-means (and, therefore, random initial cluster 
assignments) was processed with the k-means step in 11m58s.  K-means is 
enabled with the new command line flag "-doKMeans 1".  The default is 
for k-means to not be run, which means an implied "-doKMeans 0".

The code for this new engine feature is checked in to the sf.net CVS 
repository.  If there are any comments, questions, or concerns, please 
feel free to email me: th...@sp....
