Variants

Primary

DoublePenaltyNullspace

OperatorMass

OperatorTension

OperatorStiffness

OperatorRelevance

One per input axis a of a multivariate Duchon smooth: the gradient energy along axis a, Σ(∂f/∂x_a)², each with its own REML λ_a. REML shrinks an axis’s contribution toward flat only when it does not earn its keep — penalty-based ARD / variable relevance, the replacement for brittle kernel-η optimization. Emitted when scale_dims is on.

Trait Implementations

impl Clone for PenaltySource

fn clone(&self) -> PenaltySource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PenaltySource

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PenaltySource

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for PenaltySource

impl PartialEq for PenaltySource

fn eq(&self, other: &PenaltySource) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for PenaltySource

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for PenaltySource
