Enum ObjectiveType 

pub enum ObjectiveType {
    Regression,
    BinaryClassification,
}

Type of machine learning task for objective selection.

Used to categorize objectives and validate compatibility with gradient booster configuration.

Variants

Regression

Regression objectives predict continuous values.

BinaryClassification

Binary classification objectives predict probabilities for two classes.

Trait Implementations

impl Clone for ObjectiveType

fn clone(&self) -> ObjectiveType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ObjectiveType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ObjectiveType

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ObjectiveType

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

Formats the value using the given formatter.

impl PartialEq for ObjectiveType

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

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 ObjectiveType
