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 (https://hadoop.apache.org) implementation.
