Struct fbleau::estimates::nn_bound::NNBoundEstimator [−][src]
Defines an estimator that returns the NN bound by Cover&Hart.
This estimate is asymptotically guaranteed to lower bound the true Bayes risk.
Implementations
impl<D> NNBoundEstimator<D> where
D: Fn(&ArrayView1<'_, f64>, &ArrayView1<'_, f64>) -> f64 + Send + Sync + Copy,
[src]
D: Fn(&ArrayView1<'_, f64>, &ArrayView1<'_, f64>) -> f64 + Send + Sync + Copy,
pub fn new(
test_x: &ArrayView2<'_, f64>,
test_y: &ArrayView1<'_, Label>,
distance: D,
nlabels: usize
) -> NNBoundEstimator<D>
[src]
test_x: &ArrayView2<'_, f64>,
test_y: &ArrayView1<'_, Label>,
distance: D,
nlabels: usize
) -> NNBoundEstimator<D>
Create a new NN bound estimator.
Trait Implementations
impl<D> BayesEstimator for NNBoundEstimator<D> where
D: Fn(&ArrayView1<'_, f64>, &ArrayView1<'_, f64>) -> f64 + Send + Sync + Copy,
[src]
D: Fn(&ArrayView1<'_, f64>, &ArrayView1<'_, f64>) -> f64 + Send + Sync + Copy,
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.
