Summary: Allow User Defined threshold for densityAnalysys()
Key: MAHOUT-2009
URL: https://issues.apache.org/jira/browse/MAHOUT-2009
Project: Mahout
Issue Type: Bug
Affects Versions: 0.13.1
Reporter: Andrew Palumbo
Fix For: 0.13.2


Stochastic `densityAnalysis(...)` is is heavily used in the breaking down of drms to in-core matrix and rebuilding DRMs after operations:

https://github.com/apache/mahout/blob/08e02602e947ff945b9bd73ab5f0b45863df3e53/math-scala/src/main/scala/org/apache/mahout/math/scalabindings/package.scala#L431

the density is currently hard-coded to a quite high threshold (25%) this should either be lowered or should allow for the user to define a setting.
