Struct linfa_clustering::AppxDbscanHyperParams

pub struct AppxDbscanHyperParams<F: Float> { /* fields omitted */ }

The set of hyperparameters that can be specified for the execution of the Approximated DBSCAN algorithm.

Implementations

impl<F: Float> AppxDbscanHyperParams<F>

pub fn new(min_points: usize) -> AppxDbscanHyperParamsBuilder<F>

Minimum number of neighboring points a point needs to have to be a core point and not a noise point.

Defaults are provided if the optional parameters are not specified:

• tolerance = 1e-4
• slack = 1e-2

pub fn tolerance(&self) -> F

Two points are considered neighbors if the euclidean distance between them is below the tolerance

pub fn minimum_points(&self) -> usize

Minimum number of a points in a neighborhood around a point for it to not be considered noise

pub fn slack(&self) -> F

Approximation factor, allows the distance between two points for them to be considered neighbours to reach tolerance * (1 + slack)

pub fn appx_tolerance(&self) -> F
