--------------------------------------
Hello,
As Paritosh suggested, i tried specifying the -cl option while clustering. But
I am still experiencing the same problem. The number of members printed by the
clusterdumper code match the number of points generated by the
ClusterOutputPostProcessor for each cluster. Sadly this number does not match
the value 'n' for that cluster in the clusterdumper implementation.
Also while running the algorithm on a different dataset,the clustering
algorithm resulted in two clusters with the same cluster identifier..!! Also
that cluster contained some of the points twice. Any idea as to why is this
happening.?
The command used for performing the clustering job is :
bin/mahout org.apache.mahout.clustering.syntheticcontrol.meanshift.Job -x 15
-cd 5 -t1 100 -t2 30 -cl -dm
org.apache.mahout.common.distance.EuclideanDistanceMeasure -i testdata -ow -o
output
i am attaching the dataset on which i tried the clustering. Kindly give your
suggestions on it.
