Detailed Description

Result of a dimensionality reduction step.

Records which columns were selected and allows expanding a reduced-dimension projector back to the original feature space.

Constructor & Destructor Documentation

DRResult()

ppforest2::dr::DRResult::DRResult ( std::vector< int > const & selected_cols, size_t const original_size )

inline

Member Function Documentation

expand()

pp::Projector ppforest2::dr::DRResult::expand ( pp::Projector const & reduced_vector ) const

inline

Expand a reduced-dimension projector to the original space.

Places each element of reduced_vector at the position of the corresponding selected column; all other positions are zero.

Parameters

reduced_vector

Projector in the reduced space (q).

Returns

Projector in the original space (p), zero-padded.

Member Data Documentation

original_size

size_t const ppforest2::dr::DRResult::original_size

Number of columns in the original (unreduced) matrix.

selected_cols

std::vector<int> const ppforest2::dr::DRResult::selected_cols

Indices of the selected columns in the original matrix.
