Ensemble solutions are evaluated twice on creation

Reported by: mkommend Owned by: gkronber
Priority: high Milestone: HeuristicLab 3.3.6
Component: Problems.DataAnalysis Version: 3.3.6
Keywords: Cc:

Description (last modified by gkronber)

RegressionEnsembleSolutions and ClassificationEnsembleSolutions are derived from the according base class (RegressionSolution or ClassificationSolution) and their results are calculated in the base class constructor. As the evaluation works differently in ensemble solutions the results must be recalculated which leads to another evaluation of the training and test samples that can be quite costly.

  • Summary changed from Ensemble solution are evaluated twice on creation to Ensemble solutions are evaluated twice on creation

  • Status changed from new to accepted

comment:3 Changed 13 years ago by mkommend

r6588:

  • Corrected result descriptions in DataAnalysisSolution.
  • Added NMSE results in IRegressionSolution.
  • Split RegressionSolution into a concrete implementation class and an abstract base class RegressionSolutionBase that could also be used for RegressionEnsembleSolutions or CachingRegressionSolutions.
  • Moved calculation of results in specific regression solution implementations (e.g. SymbolicRegressionSolution).
