void PLearn::RepeatSplitter::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 101 of file RepeatSplitter.cc. References build_(). Referenced by setDataSet().

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

This does the actual building. Reimplemented from PLearn::Object. Definition at line 110 of file RepeatSplitter.cc. References PLearn::abs(), count, do_not_shuffle_first, PLearn::StatsCollector::finalize(), force_proportion, PLearn::StatsCollector::getCounts(), indices, k, last_n, PLearn::TVec< T >::length(), PLearn::VMat::length(), PLearn::manual_seed(), n, nsplits(), PLERROR, PLWARNING, PLearn::seed(), seed, shuffle, PLearn::shuffleElements(), PLearn::uniform_sample(), and PLearn::StatsCollector::update(). Referenced by build().

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

Declares this class' options. Reimplemented from PLearn::Object. Definition at line 70 of file RepeatSplitter.cc. References PLearn::declareOption(), and PLearn::OptionList.

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

Returns split number i. Implements PLearn::Splitter. Definition at line 295 of file RepeatSplitter.cc. References indices, k, last_n, nsplits(), PLERROR, shuffle, and to_repeat.

void PLearn::RepeatSplitter::makeDeepCopyFromShallowCopy (  map< const void *, void * > &  copies  )  [virtual]

Transforms a shallow copy into a deep copy. Reimplemented from PLearn::Splitter. Definition at line 278 of file RepeatSplitter.cc. References PLearn::deepCopyField(), and to_repeat.

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

Returns the number of sets per split. Implements PLearn::Splitter. Definition at line 318 of file RepeatSplitter.cc. References to_repeat.

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

Returns the number of available different "splits". Implements PLearn::Splitter. Definition at line 326 of file RepeatSplitter.cc. References n, and to_repeat. Referenced by build_(), and getSplit().

PLearn::RepeatSplitter::PLEARN_DECLARE_OBJECT (  RepeatSplitter   )

Declares name and deepCopy methods.

void PLearn::RepeatSplitter::setDataSet (  VMat  the_dataset  )  [virtual]

Set the dataset on which the splits are to be based. Reimplemented from PLearn::Splitter. Definition at line 334 of file RepeatSplitter.cc. References build(), and to_repeat.
