Detailed Description

Selects all variables (no variable selection).

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

Member Function Documentation

compute()

void ppforest2::vars::All::compute ( NodeContext & ctx, stats::RNG & rng ) const

overrideprotectedvirtual

Subclass implementation of variable selection.

Implements ppforest2::vars::VariableSelection.

display_name()

std::string ppforest2::vars::All::display_name ( ) const

inlineoverridevirtual

Human-readable name for display in summaries.

Implements Strategy< VariableSelection >.

from_json()

static VariableSelection::Ptr ppforest2::vars::All::from_json ( nlohmann::json const & j )

static

supported_modes()

std::set< types::Mode > ppforest2::vars::All::supported_modes ( ) const

inlineoverridevirtual

Training modes this strategy supports.

Every concrete strategy MUST explicitly declare which modes it supports — there is no default. This forces implementers to think about mode compatibility rather than silently inheriting both modes and triggering runtime surprises.

Used by TrainingSpec to validate that every selected strategy is compatible with the configured training mode. Fails fast at build time instead of silently misbehaving at train time.

Implements Strategy< VariableSelection >.

to_json()

nlohmann::json ppforest2::vars::All::to_json ( ) const

overridevirtual

Serialize this strategy's configuration to JSON.

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

Implements Strategy< VariableSelection >.
