Subject [ANN] Apache Mahout 0.2 Released
Date Wed, 18 Nov 2009 13:34:48 GMT
Apache Mahout 0.2 has been released and is now available for public
download at http://www.apache.org/dyn/closer.cgi/lucene/mahout

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
Scale in terms of computation to the
size of data you manage today.  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. 

Built on top of the powerful map/reduce paradigm of the Apache Hadoop
project, Mahout's goal is to solve popular machine learning problems
like clustering, collaborative filtering and classification
over extremely large data sets over thousands of computers.

Up to date maven artifacts can be found in the Apache repository at
https://repository.apache.org/content/repositories/releases/org/apache/mahout/

The complete changelist can be found here:
http://issues.apache.org/jira/browse/MAHOUT/fixforversion/12313278
