Struct SmartcoreF1 

pub struct SmartcoreF1 {
    pub beta: f64,
}

F1 score (harmonic mean of precision and recall) via smartcore.

Assumes binary targets encoded as 0.0 / 1.0.

Fields

beta: f64

The beta weighting (1.0 for the standard F1).

Trait Implementations

impl Clone for SmartcoreF1

fn clone(&self) -> SmartcoreF1

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SmartcoreF1

impl Debug for SmartcoreF1

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

Formats the value using the given formatter.

impl Default for SmartcoreF1

fn default() -> Self

Returns the “default value” for a type.

impl Scorer for SmartcoreF1

fn score(&self, y_true: &Array1<f64>, y_pred: &Array1<f64>) -> f64

Compute the score. y_true and y_pred are assumed equal length.

fn name(&self) -> &str

A short human-readable name (used to label CvResults columns).

fn greater_is_better(&self) -> bool

Whether a larger score is better (e.g. accuracy, R²) or smaller is better (e.g. MAE, MSE, RMSE). Defaults to true.
