virtual svm_problem* Impala::Core::Training::TrainDataSrcFeature::MakeSvmProblem ( ) [inline, virtual]

Create an svm-problem of all available data.

In case of FeatureTables all the tables in FeatureData are read to create one svm_problem. In case of distributed precomputed kernels it makes a dummy svm_problem. If Filter...Fold is called, this function wil only return a part of the whole set.

The returned structure must be deleted with FreeProblem().
