Member Function Documentation

VarArray PLearn::UnaryVariable::ancestors (   )  [virtual]

if not marked, find all Variables that influence this Variable. Implements PLearn::Variable. Definition at line 118 of file UnaryVariable.cc. References input.

void PLearn::UnaryVariable::buildPath (  VarArray &  proppath  )  [virtual]

Finally buildPath is to be called from the output Variable of interest (this will build the proppath at the same time as erasing the marks). Implements PLearn::Variable. Definition at line 88 of file UnaryVariable.cc. References PLearn::TVec< Var >::append(), PLearn::Variable::clearMark(), and input.

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

redefine this in subclasses: call declareOption(...) for each option, and then call inherited::declareOptions(options) ( see the declareOption function further down) ex: static void declareOptions(OptionList& ol) { declareOption(ol, "inputsize", &MyObject::inputsize_, OptionBase::buildoption, "the size of the input\n it must be provided"); declareOption(ol, "weights", &MyObject::weights, OptionBase::learntoption, "the learnt model weights"); inherited::declareOptions(ol); } Reimplemented from PLearn::Variable. Reimplemented in PLearn::AffineTransformWeightPenalty, PLearn::CutAboveThresholdVariable, PLearn::CutBelowThresholdVariable, PLearn::DuplicateColumnVariable, PLearn::DuplicateRowVariable, PLearn::DuplicateScalarVariable, PLearn::EqualConstantVariable, PLearn::ExtendedVariable, PLearn::IsAboveThresholdVariable, PLearn::IsMissingVariable, PLearn::MatRowVariable, PLearn::OneHotVariable, PLearn::PDistributionVariable, PLearn::PlusConstantVariable, PLearn::PowVariable, PLearn::ReshapeVariable, PLearn::SubMatTransposeVariable, PLearn::SubMatVariable, PLearn::SubsampleVariable, PLearn::UnaryHardSlopeVariable, PLearn::UnequalConstantVariable, and PLearn::VecElementVariable.

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

Reimplemented from PLearn::Variable. Reimplemented in PLearn::LogSumVariable, PLearn::MatRowVariable, PLearn::PDistributionVariable, and PLearn::VecElementVariable. Definition at line 72 of file UnaryVariable.cc. References input, and PLearn::varDeepCopyField(). Referenced by PLearn::MultinomialSampleVariable::deepCopy().

bool PLearn::UnaryVariable::markPath (   )  [virtual]

sets the marked flag of all the sVariable that are to be in the fprop path. The input sVariable that are of interest are to be marked first.
