I'm running trunk. Using the data at http://people.apache.org/wikipedia/n2.tar.gz
(a dump of 2302 documents from a Lucene index of Wikipedia. The
chunks file in that same directory contains the original files).
Vectors are normalized using L2.
When I run K-Means on it via:
org.apache.mahout.clustering.kmeans.KMeansDriver --input /Users/
grantingersoll/projects/lucene/solr/wikipedia/devWorks/n2/part-
full.txt --clusters /Users/grantingersoll/projects/lucene/solr/
wikipedia/devWorks/n2/clusters --k 10 --output /Users/grantingersoll/
projects/lucene/solr/wikipedia/devWorks/n2/k-output --distance
org.apache.mahout.utils.CosineDistanceMeasure
I get the two directories seen in n2-output. The clusters-0 and
clusters-1 files both contain a single vector which is all 0.
I've also tried SquaredEuclidean, but to no avail.
Any insight into what I'm doing wrong would be appreciated.
Thanks,
Grant
