[jira] [Commented] (MAHOUT-966) Mismatch in the number of points
given by the clusterDumper and ClusterOutputPostProcessor
[ https://issues.apache.org/jira/browse/MAHOUT-966?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13399375#comment-13399375 ]
Gaurav Redkar commented on MAHOUT-966:
--------------------------------------
yeah i can try to look into thjs issue. I want a clarification regarding the difference between the variables "numPoints" and "boundPoints" as mentioned in my previous comment above.
The point to note is that the size of "boundPoints" ("boundpoints" is a list of points belonging to a cluster) that i tried to print by tweaking the clusterdumper code actually matched the number of points printed in each cluster. so could it be that the "numPoints" was not properly calculated at the end of last iteration before the algorithm terminates..? It is just a guess. I will try to look deeper into it.

> Components: Integration
> Affects Versions: 0.6
> Environment: hadoop 0.20.2 mahout 0.6
> Reporter: Gaurav Redkar
> Priority: Minor
> Attachments: cluster-dumper-output.txt, clusterpp-output.txt, mtestdata.txt, points100dCCNorm.txt

> After running the post processor the number of points that each cluster contains is not matching the number of points each cluster should contain as stated by clusterdumper.

> MSV-287{ n=90 c=[0.05195, 0.05675, 0.07151, 0.05713, 0.06946,...}
> MSV-145{ n=90 c=[0.93685, 0.93071, 0.93641, 0.94629, 0.94409,..}
> the n mentioned in clusters-n-final against each cluster is different from the number of points actually contained in d directory for each cluster. Any idea why is this happening ...?
