Struct Precision 

pub struct Precision {
    pub class_id: Option<usize>,
}

Precision metric for classification.

Fields

class_id: Option<usize>

Class to compute precision for (None = macro average).

Trait Implementations

impl Clone for Precision

fn clone(&self) -> Precision

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Precision

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

Formats the value using the given formatter.

impl Default for Precision

fn default() -> Precision

Returns the “default value” for a type.

impl Metric for Precision

fn compute( &self, predictions: &ArrayView<'_, f64, Ix2>, targets: &ArrayView<'_, f64, Ix2>, ) -> TrainResult<f64>

Compute metric value.

fn name(&self) -> &str

Get metric name.

fn reset(&mut self)

Reset metric state (for stateful metrics).
