Detailed Description

No-op dimensionality reduction: selects all variables.

Used with standard (non-random-forest) trees where all features are available to the projection pursuit step at every node.

display_name()

std::string ppforest2::dr::DRNoopStrategy::display_name ( ) const

inlineoverridevirtual

Human-readable name for display in summaries.

Implements Strategy< DRStrategy >.

select()

DRResult ppforest2::dr::DRNoopStrategy::select ( types::FeatureMatrix const & x, stats::GroupPartition const & group_spec, stats::RNG & rng ) const

overridevirtual

Select a subset of variables.

Parameters

x	Feature matrix (n × p).
group_spec	Group partition.
rng	Random number generator.

Returns

DRResult recording which columns were selected.

Implements ppforest2::dr::DRStrategy.

to_json()

void ppforest2::dr::DRNoopStrategy::to_json ( nlohmann::json & j ) const

overridevirtual

Serialize this strategy's configuration to JSON.

Must include a "name" field identifying the strategy type, plus any strategy-specific parameters.

Parameters

j	JSON object to populate.

Implements Strategy< DRStrategy >.
