Apache Mahout is a subproject of Apache Lucene with the goal of delivering scalable machine learning algorithm implementations under the Apache license. http://www.apache.org/licenses/LICENSE-2.0

Mahout is a machine learning library meant to scale: Scale in terms of community to support anyone interested in using machine learning. Scale in terms of business by providing the library under a commercially friendly, free software license. Scale in terms of computation to the size of data we manage today.

Built on top of the powerful map/reduce paradigm of the Apache Hadoop project, Mahout lets you solve popular machine learning problem settings like clustering, collaborative filtering and classification
over Terabytes of data over thousands of computers.

Implemented with scalability in mind the latest release brings many performance optimizations so that even in a single node setup the library performs well.
