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

Implements PLearn::Variable. Definition at line 77 of file MinVariable.cc.

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

compute output given input Implements PLearn::Variable. Definition at line 64 of file MinVariable.cc. References val.

PLearn::MinVariable::PLEARN_DECLARE_OBJECT (  MinVariable   )

void PLearn::MinVariable::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 61 of file MinVariable.cc.

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

compute a piece of new Var graph that represents the symbolic derivative of this Var Reimplemented from PLearn::Variable. Definition at line 88 of file MinVariable.cc. References PLearn::argmin(), PLearn::Var::length(), and PLearn::Var::width().
