Trait fbleau::estimates::BayesEstimator[−][src]

pub trait BayesEstimator {
    fn add_example(
        &mut self, 
        x: &ArrayView1<'_, f64>, 
        y: Label
    ) -> Result<(), ()>;

    fn get_error_count(&self) -> usize;

    fn get_error(&self) -> f64;

    fn get_individual_errors(&self) -> Vec<bool>;
}

Every estimator should implement this trait.

Required methods

fn add_example(&mut self, x: &ArrayView1<'_, f64>, y: Label) -> Result<(), ()>[src]

Adds a new training example.

fn get_error_count(&self) -> usize[src]

Returns the current number of errors.

fn get_error(&self) -> f64[src]

Returns the current error rate.

fn get_individual_errors(&self) -> Vec<bool>[src]

Returns the current errors for each test point. true means error, false no error.

Implementors

impl BayesEstimator for FrequentistEstimator[src]

fn add_example(&mut self, x: &ArrayView1<'_, f64>, y: Label) -> Result<(), ()>[src]

Adds a new training example.

fn get_error_count(&self) -> usize[src]

Returns the current number of errors.

fn get_error(&self) -> f64[src]

Returns the current error rate.

fn get_individual_errors(&self) -> Vec<bool>[src]

Returns the current errors for each test point.

impl<D> BayesEstimator for KNNEstimator<D> where
    D: Fn(&ArrayView1<'_, f64>, &ArrayView1<'_, f64>) -> f64 + Send + Sync + Copy, [src]

fn add_example(&mut self, x: &ArrayView1<'_, f64>, y: Label) -> Result<(), ()>[src]

Adds a new example to the k-NN estimator's training data.

This also updates the prediction, if necessary.

fn get_error_count(&self) -> usize[src]

Returns the error count for the current k.

fn get_error(&self) -> f64[src]

Returns the error for the current k.

fn get_individual_errors(&self) -> Vec<bool>[src]

Returns the current errors for each test point.

impl<D> BayesEstimator for NNBoundEstimator<D> where
    D: Fn(&ArrayView1<'_, f64>, &ArrayView1<'_, f64>) -> f64 + Send + Sync + Copy, [src]

This implementation maps exactly that of KNNEstimator, except for get_error(), which returns the bound.

fn add_example(&mut self, x: &ArrayView1<'_, f64>, y: Label) -> Result<(), ()>[src]

Adds a new example.

fn get_error_count(&self) -> usize[src]

Returns the error count.

fn get_error(&self) -> f64[src]

Returns the error for the current k.

fn get_individual_errors(&self) -> Vec<bool>[src]

Returns the current errors for each test point.
