I am Final year BE Student from Gujarat,India. right now studying in
Information Technology Branch. i have Final Year project as Document
Clustering using Hadoop.
At this stage i am able to find final result from cluster dump command in
which i can see number of document in particular cluster and
In Weka it is possible to mark the field with a question mark ? for unknown
values and these are handled. Is there a similar way to mark
unknown/missing field values in Mahout training and test data as well.
Appreciate any suggestions/pointers. Breiman talks about two ways to handle
missing
From looking at the code recently, no it is not handled.

Also can anyone explain how the .mdtext files are eventually converted
into HTML for the current Mahout website?
I guess there is a static site generator written in Perl ( lib/view.pm
and lib/path.pm ). But what really invokes the site generation in
terms of the entry point?
I was able to
I want to analyze cluster which i did clustering on mahout by kmeans algorithm.
In qualcluster command there is an comman linne argument as -c what kind of
file i need to give as input for kmeans algorithm.
I did it for streaming kmeans. It worked. But every time i run qualcluster i am
getting
What is the error u r seeing?
the output from KMeans is (IntWritable, ClusterWritable)
and for Streaming KMeans its (IntWritable, CentroidWritable)
QualCluster may be expecting the later and hence works for Streaming KMeans.
Could u post the error u r seeing?

yes exactly sir,
it is expecting CentroidWritable.
so error is like ClassCast Exception.
i will send snapshot soon.
but can you tell me one thing that every time i run qualcluster for
Streaming KMeans it is showing different output. why it is like that ?
and as you you instructed earlier i checked
Thnks for the Replay sir,
actually i am doing clustering for gathering similar king of document in
same cluster as much as possible.
i can see from output file by cluster dump by observing top term.
i also figure out that by varying Distance Measure Technique. it differs.
but i want some
waiting for the replay sir . . . .

Sebastian created an example import around this that is really nice for several
reasons so anyone interested should check out
https://issues.apache.org/jira/browse/MAHOUT-1518, make sure to look at the
patches, the comment thread is a bit cluttered.
1) Spark is awesome because of it’s use of
