Member Function Documentation

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

Implements PLearn::Variable. Definition at line 92 of file RightPseudoInverseVariable.cc. References PLERROR.

void PLearn::RightPseudoInverseVariable::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 63 of file RightPseudoInverseVariable.cc. References build_().

void PLearn::RightPseudoInverseVariable::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. Definition at line 70 of file RightPseudoInverseVariable.cc. References PLearn::Var::length(), PLERROR, and PLearn::Var::width(). Referenced by build(), and RightPseudoInverseVariable().

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

compute output given input Implements PLearn::Variable. Definition at line 86 of file RightPseudoInverseVariable.cc. References PLearn::rightPseudoInverse().

PLearn::RightPseudoInverseVariable::PLEARN_DECLARE_OBJECT (  RightPseudoInverseVariable   )

void PLearn::RightPseudoInverseVariable::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. Reimplemented from PLearn::Variable. Definition at line 77 of file RightPseudoInverseVariable.cc. References PLearn::Var::length(), and PLearn::Var::width().

void PLearn::RightPseudoInverseVariable::symbolicBprop (   )  [virtual]

compute a piece of new Var graph that represents the symbolic derivative of this Var Reimplemented from PLearn::Variable. Definition at line 98 of file RightPseudoInverseVariable.cc. References PLERROR.
