Detailed Description

VMatrix that can be used to uniformize (between a and b) each feature in index of the underlying distribution such that: P(x') = .5 if a < x'< b = 0 otherwise

We suppose that the original distribution of x, P(x), could be anything, and we map "a" with bins[0] and "b" with bins[N-1].

Member Function Documentation

void PLearn::UniformizeVMatrix::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 65 of file UniformizeVMatrix.cc. References build_(). Referenced by UniformizeVMatrix().

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

This does the actual building. Reimplemented from PLearn::VMatrix. Definition at line 72 of file UniformizeVMatrix.cc. References a, b, bins, distr, index, PLearn::VMat::length(), PLearn::TMat< T >::length(), PLearn::TVec< T >::length(), PLearn::max(), PLearn::min(), and PLERROR. Referenced by build().

void PLearn::UniformizeVMatrix::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 88 of file UniformizeVMatrix.cc. References PLearn::declareOption(), and PLearn::OptionList.

void PLearn::UniformizeVMatrix::getNewRow (  int  i, const Vec &  v )  const [protected, virtual]

This is the only method requiring implementation in subclasses. Implements PLearn::RowBufferedVMatrix. Definition at line 98 of file UniformizeVMatrix.cc. References a, b, bins, distr, PLearn::estimatedCumProb(), index, PLearn::TVec< T >::length(), PLearn::VMatrix::length(), PLERROR, PLearn::vec_find(), and PLearn::VMatrix::width().

PLearn::UniformizeVMatrix::PLEARN_DECLARE_OBJECT (  UniformizeVMatrix   )

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

in case the dimensions of an underlying vmat has changed, recompute it Reimplemented from PLearn::VMatrix. Definition at line 94 of file UniformizeVMatrix.h. References distr, PLearn::VMat::length(), and PLearn::VMat::width().
