Expand description

Common interface for streaming classifiers.

Required Methods§

Source

fn n_features(&self) -> usize

Number of input features.

Source

fn n_classes(&self) -> usize

Number of classes.

Source

fn n_observed(&self) -> u64

Number of (features, label) samples observed so far.

Source

fn observe( &self, features: &Array1<f64>, label: usize, ) -> ClassificationResult<()>

Update the model with a single labelled observation.

Source

fn predict( &self, features: &Array1<f64>, ) -> ClassificationResult<ClassPrediction>

Produce a class prediction.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
