Performance enhancements for logistic regression (!28) · Merge requests · Moritz Aurel Pascal Schubotz / IMPRO-3-SS14

Moritz Aurel Pascal Schubotz requested to merge github/fork/markus-h/dev_stratosphere_performance-pr into master Jul 07, 2014

Created by: markus-h

We tweaked our algorithm to run faster on the cluster. Therefore we replaced a cross with a map in combination with broadcast variables. Additionally we got rid of all object creations inside of functions and replaced the former apache commons math vector clath with functions that work directly on arrays.
