Struct linfa_hierarchical::HierarchicalCluster

pub struct HierarchicalCluster<T: Float>(_);

Agglomerative hierarchical clustering

In this clustering algorithm, each point is first considered as a separate cluster. During each step, two points are merged into new clusters, until a stopping criterion is reached. The distance between the points is computed as the negative-log transform of the similarity kernel.

Implementations

impl<F: Float> HierarchicalCluster<F>

pub fn with_method(self, method: Method) -> HierarchicalCluster<F>

Select a merging method

pub fn num_clusters(self, num_clusters: usize) -> HierarchicalCluster<F>

Stop merging when a certain number of clusters are reached

In the fitting process points are merged until a certain criterion is reached. With this option the merging process will stop, when the number of clusters drops below this value.

pub fn max_distance(self, max_distance: F) -> HierarchicalCluster<F>

Stop merging when a certain distance is reached

In the fitting process points are merged until a certain criterion is reached. With this option the merging process will stop, then the distance exceeds this value.
