Detailed Description

Internal Class keeping track of which samples are support vectors and not. The first nof_sv elements in the vector are indices of the support vectors

Member Function Documentation

size_t theplu::yat::classifier::SVindex::index_first ( void  ) const
Returns
index_first
size_t theplu::yat::classifier::SVindex::index_second ( void  ) const
Returns
index_second
size_t theplu::yat::classifier::SVindex::nof_sv ( void  ) const
Returns
nof support vectors
size_t theplu::yat::classifier::SVindex::operator() ( size_t  i) const
Returns

void theplu::yat::classifier::SVindex::shuffle ( void  )

randomizes the nsv part of vector and sets index_first to nof_sv_ (the first nsv)

Returns
nof samples
size_t theplu::yat::classifier::SVindex::value_first ( void  ) const
Returns
value_first
size_t theplu::yat::classifier::SVindex::value_second ( void  ) const
Returns
value_second
