Struct linfa_clustering::AppxDbscanHyperParamsBuilder

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

Helper struct used to construct a set of hyperparameters for the approximated DBSCAN algorithm

Implementations

impl<F: Float> AppxDbscanHyperParamsBuilder<F>

pub fn tolerance(self, tolerance: F) -> Self

Distance between points for them to be considered neighbours.

pub fn slack(self, slack: F) -> Self

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

pub fn build(&self) -> AppxDbscanHyperParams<F>

Return an instance of AppxDbscanHyperParams after having performed validation checks on all hyperparameters.

Panics if any of the validation checks fail.
