Struct RingGaussianMixtureFit 

pub struct RingGaussianMixtureFit { /* private fields */ }

Certified Gaussian mixture whose component centers lie on one fitted circle.

Implementations

impl RingGaussianMixtureFit

pub fn weights(&self) -> ArrayView1<'_, f64>

pub fn center(&self) -> ArrayView1<'_, f64>

pub fn radius(&self) -> f64

pub fn directions(&self) -> ArrayView2<'_, f64>

pub fn variance(&self) -> f64

pub fn iterations(&self) -> usize

pub fn certificate(&self) -> GaussianMixtureCertificate

pub fn num_free_parameters(&self) -> usize

Free parameters: k-1 weight logits, center(2), radius(1), k component angles, and shared log standard deviation(1).

pub fn per_point_log_density( &self, data: ArrayView2<'_, f64>, ) -> Result<Array1<f64>, String>

pub fn bic(&self) -> f64

Schwarz BIC approximation to negative log evidence, divided by two so it is on the ordinary negative-log-likelihood scale. Lower is better.
