Struct GmmClusterConfig 

pub struct GmmClusterConfig {
    pub nbasis: usize,
    pub basis_type: ProjectionBasisType,
    pub cov_type: CovType,
    pub cov_weight: f64,
    pub max_iter: usize,
    pub tol: f64,
    pub n_init: usize,
    pub seed: u64,
    pub use_icl: bool,
}

Configuration for GMM-based functional clustering.

Collects all tuning parameters for gmm_cluster_with_config, with sensible defaults obtained via GmmClusterConfig::default().

Example

use fdars_core::gmm::cluster::GmmClusterConfig;
use fdars_core::gmm::CovType;
use fdars_core::basis::ProjectionBasisType;

let config = GmmClusterConfig {
    nbasis: 10,
    cov_type: CovType::Full,
    ..GmmClusterConfig::default()
};

Fields

nbasis: usize

Number of basis functions for projection (default: 5).

basis_type: ProjectionBasisType

Basis type for projection (default: Bspline).

cov_type: CovType

Covariance structure (default: Diagonal).

cov_weight: f64

Scaling factor for covariates (default: 1.0).

max_iter: usize

Maximum EM iterations per K (default: 200).

tol: f64

Convergence tolerance (default: 1e-6).

n_init: usize

Number of random initializations per K (default: 3).

seed: u64

Base random seed (default: 42).

use_icl: bool

If true, select K by ICL; otherwise by BIC (default: false).
