Struct ProxRegularSet 

pub struct ProxRegularSet {
    pub boundary_points: Vec<Vec<f64>>,
    pub radius: f64,
}

Checks approximate r-prox-regularity of a finite point set by verifying that the projection is unique in an r-tube.

Fields

boundary_points: Vec<Vec<f64>>

Points representing the boundary of the set.

radius: f64

Prox-regularity radius.

Implementations

impl ProxRegularSet

pub fn new(boundary_points: Vec<Vec<f64>>, radius: f64) -> Self

Construct a new prox-regular set.

pub fn project(&self, x: &[f64]) -> Vec<f64>

Compute projection onto the boundary point set.

pub fn has_unique_projection(&self, x: &[f64]) -> bool

Check if the projection from x is unique (only one nearest neighbour).

pub fn check_prox_regular(&self, test_points: &[Vec<f64>]) -> bool

Check prox-regularity: all points within the r-tube have unique projections.
