void PLearn::UnfoldedFuncVariable::bprop ( ) [virtual]

Implements PLearn::Variable.
Definition at line 165 of file UnfoldedFuncVariable.cc.
References PLearn::TMat< T >::column(), f_paths, input_matrix, PLearn::Var::length(), outputs, transpose, and PLearn::Var::width().

void PLearn::UnfoldedFuncVariable::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::Variable.
Definition at line 75 of file UnfoldedFuncVariable.cc.
References build_().
Referenced by UnfoldedFuncVariable().

void PLearn::UnfoldedFuncVariable::build_ ( ) [protected]

This method should be redefined in subclasses and do the actual building of the object according to previously set option fields. Constructors can just set option fields, and then call build_. This method is NOT virtual, and will typically be called only from three places: a constructor, the public virtual build() method, and possibly the public virtual read method (which calls its parent's read). build_() can assume that it's parent's build_ has already been called.
Reimplemented from PLearn::Variable.

void PLearn::UnfoldedFuncVariable::declareOptions ( OptionList & ol ) [static]

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::NaryVariable.

void PLearn::UnfoldedFuncVariable::fprop ( ) [virtual]

compute output given input

Implements PLearn::Variable.
Definition at line 145 of file UnfoldedFuncVariable.cc.
References PLearn::TMat< T >::column(), PLearn::Var::column(), f_paths, input_matrix, inputs, PLearn::Var::length(), outputs, transpose, PLearn::Vec, and PLearn::Var::width().

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

Reimplemented from PLearn::NaryVariable.
Definition at line 134 of file UnfoldedFuncVariable.cc.
References PLearn::deepCopyField(), f, f_paths, input_matrix, inputs, and outputs.

PLearn::UnfoldedFuncVariable::PLEARN_DECLARE_OBJECT ( UnfoldedFuncVariable )

void PLearn::UnfoldedFuncVariable::printInfo ( bool print_gradient ) [virtual]

Reimplemented from PLearn::NaryVariable.
Definition at line 182 of file UnfoldedFuncVariable.cc.
References PLearn::endl(), f_paths, PLearn::Variable::getName(), PLearn::Object::info(), input_matrix, PLearn::Var::length(), outputs, transpose, and PLearn::Var::width().

void PLearn::UnfoldedFuncVariable::recomputeSize ( int & l,

int & w

) const [virtual]

Recomputes the length l and width w that this variable should have, according to its parent variables.
This is used for ex. by sizeprop() The default version stupidly returns the current dimensions, so make sure to overload it in subclasses if this is not appropriate.
