       <p>Mahout's goal is to build scalable machine learning libraries. With scalable
we mean:
         <ul><li>Scalable to reasonably large data sets. Our core algorithms for
clustering, classfication and batch based collaborative filtering are implemented on top of
Apache Hadoop using the map/reduce paradigm. However we do not restrict contributions to Hadoop
based implementations: Contributions that run on a single node or on a non-Hadoop cluster
are welcome as well. The core libraries are highly optimized to allow for good performance
also for non-distributed algorithms.</li>
             <li>Scalable to support your business case. Mahout is distributed under
a commercially friendly Apache Software license.</li>
