Enum ClassWeight 

pub enum ClassWeight {
    Balanced,
    Manual(Vec<(f64, f64)>),
}

Class weighting strategy for classifiers.

Variants

Balanced

Weights inversely proportional to class frequencies: n_samples / (n_classes * count_k).

Manual(Vec<(f64, f64)>)

Manual per-class weights. Keys are class labels (as f64), values are weights.

Trait Implementations

impl Clone for ClassWeight

fn clone(&self) -> ClassWeight

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ClassWeight

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ClassWeight

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ClassWeight

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
