A trait for calculating k-means with the Hamerly algorithm.

Required methods

fn compute_half_distances(centroids: &mut HamerlyCentroids<Self>)

Find the nearest centers and compute their half-distances.

fn get_closest_centroid_hamerly(
    buffer: &[Self],
    centroids: &HamerlyCentroids<Self>,
    indices: &mut [HamerlyPoint]
)

Find a point's nearest centroid, index the point with that centroid.

fn recalculate_centroids_hamerly(
    rng: &mut impl Rng,
    buf: &[Self],
    centroids: &mut HamerlyCentroids<Self>,
    points: &[HamerlyPoint]
)

Find the new centroid locations based on the average of the points that correspond to the centroid. If no points correspond, the centroid is re-initialized with a random point.

fn update_bounds(
    centroids: &HamerlyCentroids<Self>,
    points: &mut [HamerlyPoint]
)

Update the lower and upper bounds of each point.
