Member Function Documentation

void PLearn::TrainTestSplitter::build (   )  [virtual]

Should call simply inherited::build(), then this class's build_(). This method should be callable again at later times, after modifying some option fields to change the "architecture" of the object. Reimplemented from PLearn::Object. Definition at line 74 of file TrainTestSplitter.cc. References build_().

void PLearn::TrainTestSplitter::build_ (   )  [private]

This does the actual building. Reimplemented from PLearn::Object. Definition at line 69 of file TrainTestSplitter.cc. Referenced by build().

void PLearn::TrainTestSplitter::declareOptions (  OptionList &  ol  )  [static, protected]

Declares this class' options. Reimplemented from PLearn::Object. Definition at line 57 of file TrainTestSplitter.cc. References PLearn::declareOption(), and PLearn::OptionList.

TVec< VMat > PLearn::TrainTestSplitter::getSplit (  int  i = 0  )  [virtual]

Returns split number i. Implements PLearn::Splitter. Definition at line 93 of file TrainTestSplitter.cc. References append_train, k, PLearn::VMat::length(), PLERROR, PLearn::TVec< T >::resize(), PLearn::VMat::subMatRows(), and test_fraction.

int PLearn::TrainTestSplitter::nSetsPerSplit (   )  const [virtual]

Returns the number of sets per split. Implements PLearn::Splitter. Definition at line 85 of file TrainTestSplitter.cc. References append_train.

int PLearn::TrainTestSplitter::nsplits (   )  const [virtual]

Returns the number of available different "splits". Implements PLearn::Splitter. Definition at line 80 of file TrainTestSplitter.cc.

PLearn::TrainTestSplitter::PLEARN_DECLARE_OBJECT (  TrainTestSplitter   )

Declares name and deepCopy methods.
