Struct ConfigBuilder 

pub struct ConfigBuilder { /* private fields */ }

Builder for constructing PicardConfig with a fluent API.

Implementations

impl ConfigBuilder

pub fn new() -> Self

Create a new builder with default values.

pub fn density(self, density: DensityType) -> Self

Set the density function.

pub fn n_components(self, n: usize) -> Self

Set the number of components to extract.

pub fn ortho(self, ortho: bool) -> Self

Enable or disable orthogonal constraint (Picard-O).

pub fn extended(self, extended: bool) -> Self

Enable or disable extended algorithm for mixed sub/super-Gaussian sources.

pub fn whiten(self, whiten: bool) -> Self

Enable or disable whitening.

pub fn centering(self, centering: bool) -> Self

Enable or disable centering.

pub fn max_iter(self, max_iter: usize) -> Self

Set the maximum number of iterations.

pub fn tol(self, tol: f64) -> Self

Set the convergence tolerance.

pub fn m(self, m: usize) -> Self

Set the L-BFGS memory size.

pub fn ls_tries(self, ls_tries: usize) -> Self

Set the maximum line search attempts.

pub fn lambda_min(self, lambda_min: f64) -> Self

Set the minimum eigenvalue for Hessian regularization.

pub fn w_init(self, w_init: Array2<f64>) -> Self

Set the initial unmixing matrix.

pub fn fastica_it(self, iterations: usize) -> Self

Set the number of FastICA pre-iterations.

Note: Cannot be used together with jade_it.

pub fn jade_it(self, iterations: usize) -> Self

Set the number of JADE pre-iterations.

JADE (Joint Approximate Diagonalization of Eigenmatrices) uses fourth-order cumulants and Jacobi rotations for joint diagonalization. It can provide a better warm start than FastICA for some distributions.

Note: Cannot be used together with fastica_it.

pub fn random_state(self, seed: u64) -> Self

Set the random seed.

pub fn verbose(self, verbose: bool) -> Self

Enable or disable verbose output.

pub fn build(self) -> PicardConfig

Build the configuration.

pub fn build_validated(self) -> Result<PicardConfig, PicardError>

Build and validate the configuration.

Trait Implementations

impl Default for ConfigBuilder

fn default() -> ConfigBuilder

Returns the “default value” for a type.
