If you don't specify a -k value but specify a -ci directory that
contains clusters you want to use for the prior then the ClusterIterator
will use them for kmeans and fuzzyk. You will need to create one or more
sequence files containing ClusterWritables to do this.

my question was more like how can i generate new centriods based on the
predefined points i give, as in my case i know the number of clusters and also
few points in each of the cluster.

Subject: Re: intial centriods for fuzzy k means algorithm
you could use canopy clustering from mahout to initialize centroids.
Thanks

Hi,
I have sample set of few documents of each cluster(no of clusters known
and also few documents in each cluster are known in advance). How to
initialize the centriods with known documents, so that algorithm runs using
the given data points as centriods in mahout ?
