Detailed Description

Result of a variable selection step.

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

expand()

::ppforest2::pp::Projector ppforest2::vars::VariableSelection::Result::expand ( ::ppforest2::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

size_t ppforest2::vars::VariableSelection::Result::original_size = 0

Number of columns in the original (unreduced) matrix.

selected_cols

std::vector<int> ppforest2::vars::VariableSelection::Result::selected_cols

Indices of the selected columns in the original matrix.
