Enum RobustLoss 

pub enum RobustLoss {
    None,
    Huber {
        scale: f64,
    },
    Cauchy {
        scale: f64,
    },
    Arctan {
        scale: f64,
    },
}

Robust loss applied to a residual block.

Each residual block has its own loss; per-point robustification is achieved by using one residual block per observation.

Variants

None

No robustification (plain squared residual).

Huber

Huber loss with transition scale.

Fields

scale: f64

Scale parameter controlling quadratic-to-linear transition.

Cauchy

Cauchy loss with scale parameter.

Fields

scale: f64

Scale parameter controlling outlier down-weighting.

Arctan

Arctangent loss with bounded influence.

Fields

scale: f64

Scale parameter controlling curvature.

Trait Implementations

impl Clone for RobustLoss

fn clone(&self) -> RobustLoss

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RobustLoss

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

Formats the value using the given formatter.

impl Default for RobustLoss

fn default() -> RobustLoss

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RobustLoss

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RobustLoss

fn eq(&self, other: &RobustLoss) -> 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 RobustLoss

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for RobustLoss

impl StructuralPartialEq for RobustLoss
