Struct HybridSplitSelection 

pub struct HybridSplitSelection {
    pub atoms: Vec<HybridAtomChoice>,
    pub total_negative_log_evidence: f64,
    pub total_parameters: usize,
    pub curved_atom_count: usize,
}

The evidence-selected split for a whole hybrid dictionary: the per-atom curved-vs-linear choices and the dictionary-level aggregates the EV-vs-Θ frontier reports against.

Fields

atoms: Vec<HybridAtomChoice>

One adjudicated choice per atom slot, in slot order.

total_negative_log_evidence: f64

Σ NLE across the selected per-atom parameterizations — the dictionary’s summed rank-aware Laplace negative-log-evidence (lower wins). Because each slot picks the argmin over {curved contribution, best straight line to the response residual}, this is ≤ the sum of the per-slot LINEAR-candidate NLEs. The linear baseline is the best straight line fit to each atom’s leave-this-atom-out RESPONSE residual (#1202), the curved family’s nested Θ = 0 member on common data — so this is a genuine data-level match-or-beat dominance, not a post-hoc curve-simplification one.

total_parameters: usize

Σ P across the selected parameterizations — the dictionary’s total free-parameter price (the matched-active-budget accounting).

curved_atom_count: usize

Count of slots that selected the curved parameterization.

Implementations

impl HybridSplitSelection

pub fn linear_atom_count(&self) -> usize

Count of slots that selected the linear special case (the linear tail).

pub fn is_pure_linear(&self) -> bool

true iff every slot selected linear — the pure-linear limit, reached when every feature is straight (all Θ → 0).

pub fn is_pure_curved(&self) -> bool

true iff every slot selected curved — the pure-curved limit, reached when every feature turns enough to pay for curvature.

Trait Implementations

impl Clone for HybridSplitSelection

fn clone(&self) -> HybridSplitSelection

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HybridSplitSelection

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
