Which cluster does instance A belong to

Hello,

I had clustered text via COBWEB clustering.
The result seems very neat; however,
I couldn't seem to be able to know which cluster does any specific instance falls in.

Is it possible to learn such information from weka?


Thanks in advance,

You could use the AddCluster filter (package
weka.filters.unsupervised.attribute) to add the cluster to the
instances they got assigned to. In the Explorer, display the cluster
assignments and save them as ARFF file. That will also generate a
dataset with an additional attribute listing the cluster an instance
was assigned to.

Cheers, Peter
