Positive class value setting from classification problems is not set correctly in classification ensemble solutions

Reported by: gkronber Owned by: bburlacu
Priority: medium Milestone: HeuristicLab 3.3.17
Component: Algorithms.DataAnalysis Version:
Keywords: Cc:

Description

Steps to reproduce:

  • New RF for classification
  • Load UCI problem 'Iris'
  • Set positive class value to 'Class 2'
  • Load algorithm into cross-validation and run
  • The positive class value for the resulting ensemble solution is 'Class 0'

The problem was that the CrossValidation class did not use the regular cloning mechanism to obtain a copy of the problem data, because it also needed to shuffle the dataset. the positive class parameter was missing from the ad-hoc cloning code. Fixed with r17833.
