#3044 reviewing enhancement

Add scaling of input features

Reported by: djoedick Owned by: gkronber
Priority: medium Milestone: HeuristicLab 3.3.17
Component: Problems.DataAnalysis Version: branch
Keywords: Cc:


Investigation of ticket #3043 has shown, that scaling of input variables often leads to an improvement in the quality of the results, especially when using a standard deviation. This feature should be implemented as a standard option for upcoming versions.
