Hudson commented on MAHOUT-766:
-------------------------------
Integrated in Mahout-Quality #1101 (See
[https://builds.apache.org/job/Mahout-Quality/1101/])
MAHOUT-766: Changed m argument to 1.1 and switched Dirichlet to use
clustering vs. classifier implementation. Added cosine distance measure to
reuters kmeans.

> believe there is something wrong with fkmeans in trunk.
> I am using code from trunk (last checkout 6/30/11). To recreate is very
> simple:
> 1) change examples/bin/build-reuters.sh to use fkmeans and set -m 2
> 2) run build-reuters.sh
> 3) Dump the cluster. I'm doing: ../../bin/mahout clusterdump -dt sequencefile
> -s ./mahout-work/reuters-kmeans/clusters-6 -b 100 -o
> ./reuters-clusterdump.txt -d
> ./mahout-work/reuters-out-seqdir-sparse-kmeans/dictionary.file-0
> here is what the clusters look like:
