Does anyone know an approach to performing model selection in Weka through cross validation for regression problems?

As far as I can tell, the cross validation is implemented in Weka just to assess the performance of the classifier. I guess that calling Weka API from Java might solve the problem, but is there a GUI-based approach?

    $\begingroup$ Compared to the message posted on weka ml (notwithstanding the cross-post on MetaOptimize), do you mean you want to compare different regression models, or just to optimize a given model with e.g., cross-validation? $\endgroup$ – chl May 2 '11 at 6:40

    $\begingroup$ @chl In fact he should do both to get reliable results =) $\endgroup$ – user88 May 2 '11 at 8:45
  • $\begingroup$ @mbq is right. However, the first step is to optimize some specific regression models. @chl: unfortunately, the weka ml community didn't come with a useful response. $\endgroup$ – lmsasu May 2 '11 at 9:33
