> Project: Mahout
> Issue Type: New Feature

> Good morning.
> As part of my final year project, I have implemented a new module for Apache
> Mahout, implementing Kohonen's self-organizing map algorithm, in its batch
> version.
> The work is already done, and I will proceed to submit a patch ASAP. It was
> developed over Mahout 0.8.
> The patch includes unit tests and the algorithm was successfully used in a
> Hadoop cluster to cluster two big datasets. Results can be seen in [this
> image gallery|http://imgur.com/a/DlgRT].
> The implementation uses the generic clustering algorithms implemented in the
> ClusterIterator class. Minor changes were made to this and other related
> classes to support some of the features, without affecting the execution of
> other algorithms.
> The algorithm supports convergence and the ability to resume a work at a
> given iteration (mainly, in order to initialize KohonenBatchClusteringPolicy
> with a given iteration number, althought it also affects the names of the
> output directories).
