  • Ticket #2623

    • Property Summary changed from Exception when dropping a new problem data onto the simplified view for regression solutions to Exception when dropping a new problem data onto the simplifier view for regression solutions
    • Property Milestone changed from HeuristicLab 3.3.14 to HeuristicLab 3.3.15

  • Ticket #2623 – Description

    initial v2  
    11It is possible to drop ProblemData objects onto regression solutions to evaluate a particular solution on a new dataset. In this case the dataset is changed so that the test partition contains all observations (there is no training partition).
    22
    3 However, the view for the simplified calculates node impacts based on training samples only and since there are no training samples in this case an exception occurs.
     3However, the simplifier view calculates node impacts based on training samples only and since there are no training samples in this case an exception occurs.

    55(It is also not possible to optimize parameters using the structure of the current solution to fit the parameters to the new dataset)
