Struct KMeansConfig 

pub struct KMeansConfig {
    pub k: usize,
    pub max_iters: usize,
    pub tol: f64,
    pub seed: u64,
    pub max_points_per_centroid: Option<usize>,
    pub chunk_size_data: usize,
    pub chunk_size_centroids: usize,
    pub verbose: bool,
}

Configuration for the FastKMeans algorithm

Fields

k: usize

Number of clusters

max_iters: usize

Maximum number of iterations

tol: f64

Convergence tolerance. When centroid shift is below this threshold, the algorithm stops early. Set to negative value to disable early stopping.

seed: u64

Random seed for centroid initialization and subsampling

max_points_per_centroid: Option<usize>

Maximum points per centroid for subsampling. If n_samples > k * max_points_per_centroid, data will be subsampled. Set to None to disable subsampling.

chunk_size_data: usize

Chunk size for data processing. Larger values use more memory but may be faster.

chunk_size_centroids: usize

Chunk size for centroid processing. Larger values use more memory but may be faster.

verbose: bool

Print verbose output during training
