Apache Mahout is a subproject of Apache Lucene with the goal of

> delivering scalable machine learning algorithm implementations under

> the Apache license.

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.
