description A scalable machine learning library that supports large data sets
long_description Mahout is a scalable machine learning library that implements many \
different approaches to machine learning. \
The project currently contains implementations of algorithms for \
classification, clustering, genetic programming and collaborative \
filtering, all enabled to scale by leveraging the power of Hadoop's \
Map-Reduce (http://hadoop.apache.org) implementation.
