Detailed Description

Split threshold as the mean of two group means.

Computes the midpoint between the projected means of the two groups: (mean(group_1 * A) + mean(group_2 * A)) / 2. This is the default rule used by PPforest.

◆ display_name()

std::string ppforest2::sr::SRMeanOfMeansStrategy::display_name ( ) const

inlineoverridevirtual

Human-readable name for display in summaries.

Implements Strategy< SRStrategy >.

◆ from_json()

◆ threshold()

types::Feature ppforest2::sr::SRMeanOfMeansStrategy::threshold	(	types::FeatureMatrix const &	group_1,
		types::FeatureMatrix const &	group_2,
		pp::Projector const &	projector ) const

overridevirtual

Compute the split threshold for two groups.

Parameters

group_1	Feature matrix for the first group (n1 × p).
group_2	Feature matrix for the second group (n2 × p).
projector	Projection vector (p).

Returns: Scalar threshold in the projected space.

Implements ppforest2::sr::SRStrategy.

◆ to_json()

void ppforest2::sr::SRMeanOfMeansStrategy::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< SRStrategy >.
