[jira] Created: (MAHOUT-28) EM implementation
EM implementation
-----------------
Key: MAHOUT-28
URL: https://issues.apache.org/jira/browse/MAHOUT-28
Project: Mahout
Issue Type: New Feature
Components: Classification
Reporter: Isabel Drost
One quarter of the work that could be done for Mahout-4. EM seems a bit to general a concept to be implemented only for the use case of PLSI, so the task of this issue is to find a way to implement EM general enough to be reused. As EM conceptually is related to k-Means it might be possible to make the implementation general enough to include k-Means as a special case.

---------------------------------
Am I understanding that since MAHOUT-4 is to be mothballed, its dependent issues like this should be too?
