[ https://issues.apache.org/jira/browse/MAHOUT-1081?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Smita Wadhwa updated MAHOUT-1081:
---------------------------------
Description:
Precision of vectors containing data like 0.00167328372 and 0.000829739 , 0.001783978978 will end up in output as 0.001,0.000, 0.001 when specially vector id has also been lost in clustering after kmeans , its really difficult to get back the original data.
