Detailed Description

like PairVMatrix but samples from all the pairs in order (traversing all the nxn pairs), outputs a Vec that is the concatenation of the i-th row of data1 and j-th row of data2. The j-index moves faster than the i-index.

Member Function Documentation

void PLearn::PairsVMatrix::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::VMatrix. Definition at line 62 of file PairsVMatrix.cc. References build_().

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

This does the actual building. Reimplemented from PLearn::VMatrix. Definition at line 69 of file PairsVMatrix.cc. Referenced by build().

void PLearn::PairsVMatrix::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::VMatrix. Definition at line 74 of file PairsVMatrix.cc. References PLearn::declareOption(), and PLearn::OptionList.

void PLearn::PairsVMatrix::getNewRow (  int  ij, const Vec &  samplevec )  const [protected, virtual]

This is the only method requiring implementation in subclasses. Implements PLearn::RowBufferedVMatrix. Definition at line 81 of file PairsVMatrix.cc. References PLearn::TVec< T >::data(), data1, data2, k, PLearn::TMat< T >::length(), and PLearn::Vec.

PLearn::PairsVMatrix::PLEARN_DECLARE_OBJECT (  PairsVMatrix   )

virtual void PLearn::PairsVMatrix::reset_dimensions (   )  [inline, virtual]

in case the dimensions of an underlying vmat has changed, recompute it Reimplemented from PLearn::VMatrix. Definition at line 87 of file PairsVMatrix.h. References PLERROR.
