pub enum ValidationMetric

Validation losses averaged over held-out observations; lower is better.

Prediction inputs are original-scale linear predictors, including logits for binomial scores. Scores exclude the penalty and use no training-size correction. Binomial deviance subtracts the fractional-response saturated loss before doubling, whereas log loss is the negative log likelihood.

Variants

BinomialDeviance

Source: src/cross_validation/metric.rs

BinomialDeviance

Binomial mean deviance, twice the excess loss above saturation.

LogLoss

Source: src/cross_validation/metric.rs

LogLoss

Binomial mean negative log likelihood, evaluated stably from logits.

MeanAbsoluteError

Source: src/cross_validation/metric.rs

MeanAbsoluteError

Gaussian mean absolute prediction error.

MeanSquaredError

Source: src/cross_validation/metric.rs

MeanSquaredError

Gaussian mean squared error, twice the fitting loss.

Inherent implementation

impl ValidationMetric

score

Source: src/cross_validation/metric.rs

pub fn score(self, response: &[f64], predictor: &[f64]) -> Result<f64, FitError>

Evaluate a score on equally weighted held-out observations.

Errors

Reject empty or mismatched inputs, invalid responses, and nonfinite predictors or arithmetic. Binomial responses must lie in [0, 1].
