Boolean parameter for data-analysis algorithms to disable creation of a final solution

Reported by: gkronber Owned by: gkronber
Priority: medium Milestone: HeuristicLab 3.3.13
Component: Algorithms.DataAnalysis Version: 3.3.11
Keywords: Cc:


For multiple data-analysis algorithms the creation (+evaluation) of the final solution takes a lot of time.

Especially, when cross-validation is used this is however not necessary and only slows down CV. Therefore, it would be useful to add a Boolean (hidden) parameter to those algorithms to turn of creation of solutions.

The following algorithms would benefit:

  • Random forest
  • Gaussian process
  • Support vector machine

r12934: added a Boolean "CreateSolution" parameter for support vector machine algorithms and added model error/accuracy metrics as algorithm results (to allow grid search without creating solutions)

r13204: added CreateSolution flag to random forest

r13205: added CreateSolution flag to Gaussian process algorithms

In the case of Gaussian process regression, it would be possible to exchange the solution creator of the problem. However, this cannot be easily achieved in the current version because of backwards-compatibility reasons. Therefore, I decided to use the same way of implementing this as for the other algorithms.

Please review the 3 changesets.

The flag has been added to

  • SVM regression & classification
  • RF regression & classification
  • Gaussian process regression & classification

The flag was already available for gradient boosted trees for regression.
