Detailed Description

This VMat is built from 2 other (possibly identical) VMats and a Kernel K. The resulting VMat takes every sample (x_i,y_i)

Member Function Documentation

void PLearn::KernelVMatrix::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 74 of file vmat/KernelVMatrix.cc. References build_().

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

This does the actual building. Reimplemented from PLearn::VMatrix. Definition at line 81 of file vmat/KernelVMatrix.cc. References d1, d2, input1, input2, PLearn::TVec< T >::resize(), and PLearn::VMat::width(). Referenced by build().

void PLearn::KernelVMatrix::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::VMatrix. Definition at line 90 of file vmat/KernelVMatrix.cc. References PLearn::declareOption(), and PLearn::OptionList.

virtual real PLearn::KernelVMatrix::get (  int  i, int  j )  const [virtual]

returns element (i,j) Reimplemented from PLearn::VMatrix.

real PLearn::KernelVMatrix::get (  int  i, int  j )  const [virtual]

returns element (i,j) Reimplemented from PLearn::VMatrix. Definition at line 81 of file ker/KernelVMatrix.cc. References d1, d2, input1, input2, ker, PLearn::VMatrix::length(), PLERROR, and PLearn::VMatrix::width().

virtual void PLearn::KernelVMatrix::getSubRow (  int  i, int  j, Vec  v )  const [virtual]

fills v with the subrow i lying between columns j (inclusive) and j+v.length() (exclusive) Reimplemented from PLearn::VMatrix.

void PLearn::KernelVMatrix::getSubRow (  int  i, int  j, Vec  v )  const [virtual]

fills v with the subrow i lying between columns j (inclusive) and j+v.length() (exclusive) Reimplemented from PLearn::VMatrix. Definition at line 94 of file ker/KernelVMatrix.cc. References d1, d2, input1, input2, ker, PLearn::TVec< T >::length(), PLearn::VMatrix::length(), PLERROR, and PLearn::VMatrix::width().
