Struct tpe::density_estimation::HistogramEstimator

pub struct HistogramEstimator { /* fields omitted */ }

Histogram based density estimation.

This can be used for categorical parameters.

Note that this estimator assumes that each told value is the index, not the raw value, of a categorical parameter.

Trait Implementations

impl Debug for HistogramEstimator

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

Formats the value using the given formatter.

impl DensityEstimator for HistogramEstimator

fn log_pdf(&self, x: f64) -> f64

Estimates the log probability density of a sample.

impl Distribution<f64> for HistogramEstimator

fn sample<R: Rng + ?Sized>(&self, rng: &mut R) -> f64

Generate a random value of T, using rng as the source of randomness.

fn sample_iter<R>(self, rng: R) -> DistIter<Self, R, T> where
    R: Rng, 

Create an iterator that generates random values of T, using rng as the source of randomness.

fn map<F, S>(self, func: F) -> DistMap<Self, F, T, S> where
    F: Fn(T) -> S,
